Using technology akin to X-ray vision, scientists can read closed books, identifying letters printed on stacks of paper up to nine sheets thick.
This finding could lead to office machines that can scan reams of paper at once, or help researchers scan ancient books that are too fragile to open. The researchers also said it could perhaps help spies read mail without opening envelopes.
The prototype device uses terahertz radiation, the band of electromagnetic radiation between microwaves and infrared light. Previous research has found that terahertz rays, or T-rays, possess a number of advantages over X-rays, ultrasound waves and other kinds of radiation that can penetrate surfaces. For instance, terahertz rays can distinguish between ink and blank paper in a way that X-rays cannot. They can also scan across depths to yield higher-resolution images than ultrasound can accomplish, according to the researchers.
The new system relies on how different chemicals absorb different frequencies of terahertz radiation to varying degrees, the scientists said. As such, it can tell the difference between paper that has ink on it versus paper that does not.
Moreover, the new system exploits the fact that air and paper each bend light to a different degree, and that pages of a book trap air pockets between them. These pockets may only be about 20 microns deep — about one-fifth of the average width of a human hair — but this can be enough for the device to distinguish the signals from different pages of a book, the researchers said.
The researchers used a terahertz camera to scan a stack of card-size, 300-micron-thick sheets of paper. Each had a single letter about 0.3 inches (8 millimeters) wide written on only one side in pencil or ink.
The scientists developed algorithms to interpret the often distorted or incomplete images from the camera as individual letters. In experiments, the prototype correctly read the nine letters T, H, Z, L, A, B, C, C and G from the front to the back of a nine-page stack, the researchers said.
“The system we used was not necessarily a top-of-the-line system — if the system was improved further, we’d have a chance of reading even deeper,”study co-author Barmak Heshmat, an electrical engineer at MIT, told Live Science.
One application of this work could involve reading ancient and fragile texts.
“The Metropolitan Museum [of Art] in New York showed a lot of interest in this, because they want to, for example, look into some antique books that they don’t even want to touch,” Heshmat said in a statement.
Another possibility of greater use in daily life may be “future scanners that can scan through large amounts of documents without having to mechanically separate the pages, which could be useful for libraries, banks and others,” Heshmat said. “Such a future scanner wouldn’t use terahertz waves, but perhaps infrared light.”
It might even be possible for spies to use this technology to peer through envelopes. Still, “it could be possible to use ink that is not visible in the frequency ranges used,” Heshmat said.
Other potential industrial applications may include analyzing any materials organized in thin layers, such as layers of paint or coatings on machine parts or pharmaceuticals, Heshmat said.
Samsung to invest $115 billion in its foundry business by 2030
Samsung is earmarking $9.5 billion a year for Samsung LSI and Samsung Foundry.
Samsung Electronics is one of the largest semiconductor players around, and the manufacturer is investing $115 billion (133 trillion won) over the next 12 years to take on Qualcomm and Intel. Samsung says its goal is to become the world leader in semiconductors and logic chips, and the company will invest $9.5 billion a year from now through 2030.
Samsung will invest $63.4 billion (73 trillion won) toward domestic R&D — where it is looking to add 15,000 jobs to “bolster its technological prowess” — and spend $52 billion (60 trillion won) toward production facilities that will make the logic chips. Samsung has long been the dominant player in the memory business, but with that market shrinking the South Korean manufacturer will be looking to diversify.
While the $115 billion seems like a staggering amount at first, it’s in line with what Samsung has been spending in recent years. Just last year alone Samsung invested over $15 billion in R&D, and Intel also spent over $10 billion toward developing new products.
LG V50 ThinQ 5G launch in South Korea delayed
The delay is due to LG wanting to further optimize the Qualcomm Snapdragon 855 chipset and Qualcomm X50 5G modem inside of the V50. LG also said it’s working with Qualcomm and South Korean carriers to improve 5G service and phone interoperability.
LG V50 ThinQ 5G price & release date: What we know so far (it’s not much)
LG didn’t say when the V50 will be available in South Korea. Android Authority reached out to LG for comment on a new release date and whether the delayed launch in South Korea will affect the U.S. launch, but did not receive a response by press time.
The delay comes at a bad time for LG, which saw rival Samsung launch its first 5G smartphone April 5 in South Korea. LG likely had hoped to use the Galaxy S10 5G’s launch momentum for its own 5G smartphone, but now we don’t know when the V50 will debut.
That said, LG might have dodged a very big bullet by delaying the V50’s launch. Business Koreareported last week that Galaxy S10 5G owners have struggled with poor 5G connectivity and an inability to switch to 4G LTE. Samsung pushed out an update that supposedly addressed the issues, but the update didn’t help much.
Samsung snubs Apple on 5G modem supply, leaving few good options for the 2020 iPhones
Thanks to the patent war with Qualcomm reaching a crescendo mode, last year Apple’s iPhones shipped exclusively with “Intel inside” as far as cellular connectivity is concerned. That, however, is not an ideal solution for Apple, as Intel’s modems are behind the curve when it comes to features, so it has been shopping around for other options.
Apple could go with Samsung, Huawei or MediaTek’s 5G modems, but each of those choices comes with severe drawbacks. Samsung will likely charge an arm and a leg for its 5G brainchild, America’s homeland security institutions would balk at Huawei’s involvement due to geopolitical considerations, while MediaTek simply isn’t up to par yet.
SAMSUNG’S 5G MODEM OPTION IS OUT FOR APPLE, BUT WHOSE IS IN?
Surprise, surprise, even those unpalatable options have now become harder to pick from, as Korean media is reporting today that Samsung has declined Apple’s advances for its Exynos 5100 5G modem. Not only does the company need its production for the Galaxy S10 5G that will be shipping tomorrow in Korea but it could very well need it for the Note 10, too.
Samsung, it turns out, is simply unable to churn out 5G modems in the quality and quantity that Apple would demand, or so it claims. According to one “electronics industry official” there:
Apple inquired about the supply of 5G modem chip from Samsung Electronics System LSI division. However, we know that Samsung Electronics System LSI answered that the supply volume of its smartphone 5G modem chip is insufficient.
There you have it – unless Apple resolves the bad blood between the companies, Qualcomm is likely to sit its 5G push out, so the last remaining option is for Apple to go it alone, either by acquiring Intel’s wireless modem assets or starting from scratch (highly unlikely). All of these options mean either a lot of extra expenses for Apple in order to deliver a 5G iPhone in 2020, or falling behind the competition by launching one that is a cycle or two behind.
Last summer, insiders claimed that they have seen internal Intel communication regarding a memo that Apple sent Chipzilla. In it, Apple warns that it might no longer need Intel’s wireless modem designs, including the 5G ones, starting with the 2020 iPhone crop. Intel reportedly halted research in this area and might disband the whole 5G modem undertaking, as Apple was its largest and perhaps sole customer.
5G gets going and Apple’s 2020 iPhones can’t go FOMO
South Korea just launched its nationwide 5G network, with the Galaxy S10 5G being its poster child. Upon the phone’s release there tomorrow, Korea will have all of its largest networks offering 5G plans. In fact, Korea Telecom announced three 5G price tiers. Among those, there is a “Super Plan” that offers truly unlimited 5G data without speed caps, and this one will go for the equivalent of $70, a pretty good price no matter how you slice it. In fact, the Super 5G Plan is somewhat cheaper than the current unlimited 4G LTE plans in Korea, so the 5G future seems bright, and we are expecting more and more 5G handsets to enter the fray this year, especially towards the tail end of 2019.
A true nationwide shift to 5G networks is not happening this year in the US anyway, so iPhone users won’t be missing all that much until then. Next year, however, most of the flagship phones of the spring season will probably have some sort of 5G connectivity support, be it with a Qualcomm, Samsung or Huawei modem, and Apple could feel the pinch in that regard. If in the fall of 2020 Apple hasn’t solved its 5G modem supply options, however, there might be image and perception consequences. As virtually all of Apple’s 5G avenues have dried up and will incur extra expenses, patching thing up with Qualcomm would be a smart solution so we’ll keep our eyes on the patent lawsuit as it moves through the court system.
