Scientists achieve X-ray vision with safe, visible light
If you think X-rays and other forms of radiation have a monopoly on penetrating opaque objects, visible light begs to differ. It actually can pass through things like paint and human tissue, which has powerful implications for medical research and other fields. Regular lightwaves could one day replace X-rays or even allow scientists to remove tumors with lasers instead of risky surgery. The problem is, such light is either absorbed or scattered once it passes through non-transparent items -- making it useless for imaging. Or is it? According to Nature, scientists are honing methods to reassemble scattered light that passes through opaque objects to create a usable image on the other side, Superman-style.
Pioneer shows off see-through projection tech for Minority Report-style signage
If Pioneer has its way, basic window-shopping might soon freak you out thanks to its latest see-through projection prototype. The tech features 80 percent transmittance levels -- supposedly much higher than transparent IPS LCD tech -- meaning bright images can be beamed onto the panels without blocking the view of objects behind. Even blacks from the rear-mounted projectors are see-through, and Pioneer envisions the tech being used one day for digital signage and improved vehicle HUDs. We're all for the latter, but the signage demo in the video after the break kind of makes us feel like ads in our head aren't far behind.
Sharp unveils semi-transparent solar panels, lets you see the sun while reaping its benefits
Sharp has announced an unusual photovoltaic panel for the Japanese market that collects energy from the sun while still allowing the light to shine on through. Though it's rated at a lowly 6.8 percent / 98 watt max efficiency, the glass-like properties make it useful as a construction material (as shown in the balcony railing above), with the semi-transparent nature giving occupants privacy, to boot. The energy-producing cells are embedded in a laminated glass structure and an air slot provides a thermal barrier, allowing the panels to also be used as "windows, curtain wall and eaves" according to Sharp's PR. Though the system won't win any potency prizes, it has garnered a design award in Japan, so it won't blight any landscapes. There's no mention of pricing or western availability so far, but you can hit the source for all the technical details.
UCLA creates transparent solar cell, dreams of current generating windows
Transparent photovoltaics have yet to grace the face of your smartphone, but don't give up hope -- UCLA researchers are working on a new see-through solar cell that's showing potential. Using a new type of polymer solar cell, the team has been able to build a device that converts infrared light into electrical current. Current prototypes boast 4 percent energy conversion efficiency at 66 percent transparency -- not crystal clear, but certainly clean enough to peer through. According to a study in ACS Nano, the technology could be used in "building-integrated photovoltaics or integrated photovoltaic chargers for portable electronics." Translation? It could one day be used to build solar windows or better sun collecting smartphones. Don't get too excited though, the technology still has a ways to go before any of these dreams come to fruition. Still, feel free to head past the break for the team's official press release, or skip to the source to take in the full academic study.
TDK starts mass production of transparent OLEDs, makes texting and walking safer
TDK is taking those transparent OLED screens we saw back in October and putting them into mass production. The 2.4-inch, QVGA (240 x 320) UEL476 display has a transmittance of 40 percent, but obscures light passing through the front so others won't be able to read your text messages from behind. Obviously, these aren't going to find their way into high-end Android handsets, but they may have a home in fashion phones like Lenovo's S800. And, you know, they seem perfect for SMS addicts who can't stop their thumbs from flying even while walking. Check out the full PR after the break.
Samsung's 22-inch Transparent BLU LCD TV shipping next week, eyes-on at SID 2011 (video)
We weren't actually allowed to get our hands on Samsung's 22-inch Transparent BLU LCD TV -- the showcase was accompanied by a "Do not touch" label -- but we were able to get our first in-the-flesh look at the see-through display at SID this week. According to Sammy's rep, the monitors, which can operate with or without a backlight, will start shipping to manufacturers as soon as this week, but consumers will have to wait until Q3 to get their hands on one. While our hands remained mostly at our sides during our little meeting, we did sneak them behind the display to see just how transparent these things are. Sure enough, we could see our phalanges wiggling quite clearly through the ghostly panel. When the backlight was flipped on, the screen became a touch more opaque, but didn't fully obstruct the view of the potted plants lurking in the background. For now, the screens are focused on the commercial market -- specifically advertising -- but we wouldn't mind adding one of these things to our living room. Hop on past the break for a little video love. %Gallery-123858%
Sony's see-through Alpha DSLR gets the hands-on treatment, probably won't get a launch date
We've been teasing you with images of this see-through beauty since Sony announced plans to bring its translucent mirror to the A77. Unfortunately, we've still yet to get our dirty paws on its hard shell, but we're happy to live vicariously through Pocket-lint's hands-on of Sony's clear-bodied Alpha camera. According to its post, the concept DSLR is based on a heretofore unidentified mid-range camera that touts an Exmor APS HD CMOS sensor and "fast continuous autofocus." The camera is slated for a late 2011 release, but chances are it won't come with that sweet transparent body. So soak it up while you can, because this could be the last you see of the crystalline casing -- hit the source link for even more eye candy.
Handheld millimeter / microwave camera to see through walls, your underpants (video)
You know those scanners that peep your naughty bits at the airport? Well, a team of researchers have been working on a handheld camera that sports the same technology, and while they're touting its future impact on stuff like cancer detection and aerospace engineering, we can't help but squirm thinking about its Peeping-Tom potential. The camera currently takes 30 images per second by transmitting millimeter and microwaves to a "collector" on the other side of a subject, and then sends them to a laptop for real-time inspection. Aside from being able to see straight through your BVDs, it can also be used to detect defects in spacecraft insulation, find termites lurking in the walls of your apartment, and help in the diagnosis of skin disease. The camera's creators are working on a smaller, one-sided version of the device that could have mass-market appeal -- we just hope this thing stays in R&D long enough for us to get our bikini bodies back. Check out a video of its G-rated abilities after the break.
TDK's see-through and curved OLED display eyes-on (video)
Remember the Sony Ericsson Xperia Pureness? At a list price of $1,000, it'd be hard to forget -- but with a monochrome see-through display, the whole transparency thing was little more than a novelty on a phone that served little practical purpose. TDK might have the solution with its new transparent QVGA OLEDs, available now to manufacturers in monochrome and in a lovely color variant by the end of the year. At two inches, they offer 200ppi pixel density and are more secure than you might think: the light only shines in one direction, so you actually can't see any data from the back even though you can still see through the display. At a glance, the display's didn't seem as vibrant as the best AMOLEDs on the market, but then again, these are passive matrix -- and you can really tell in our videos after the break where the refresh scans stand out. Guess that's the price you pay for transparency, right? We've also got some video of the 3.5-inch flexible OLED screens TDK's got on hand; they're not transparent, but considering the long, narrow resolution, we can't help but think they'd make for amazing wristwatches (or high-tech glowstick replacements at raves). %Gallery-104249%
See-through LCD screen developed
Tokyo-based optical component maker Active Inc. has developed a new composite LCD display that allows a user to clearly see objects through the monitor's viewing surface. The company has been researching the use of liquid crystal optical film as a substitute for traditional LCD backlights with the goal of commercializing a display which allows a user's gaze to pass through to the opposite side when the screen is powered on. The company is hoping to market the screens to the amusement industry, where they will be used for activities such as watching your family while watching a movie, watching a movie while another movie plays in the distance, and of course playing a video game while watching a movie.
