Nature inspires color-sensitive, CMOS-compatible photodetector

Researchers at Rice University's Laboratory for Nanophotonics (LANP) have developed a new image sensor that mimics the way we see color by integrating light amplifiers and color filters directly onto the pixels. The new design enables smaller, less complex, and more organic designs for CMOS (complementary metal-oxide semiconductor) sensors and other photodetectors used in cameras. Read More

Review: Knog's Qudos Action camera light for GoPro Hero

We've seen a plethora of accessories for the GoPro Hero actioncam cropping up over the past few years, including everything from stabilizers to drones to helmet-mounted poles. Surprisingly, though, except for scuba-specific models, there's been almost nothing in the way of lights. Australian bike gadget manufacturer Knog recently set out to fill that void, by releasing its Qudos Action light earlier this month. I recently had a chance to get my hands on the thing, and liked what it had to offer. Read More

10 Gbps Li-Fi system shows wireless data transfer in a new light

Light might be the preferred option for transmitting data over long distances via cables, but when it comes to short range wireless, radio waves rule in the form of Wi-Fi and Bluetooth. Now Mexican company Sisoft, working with researchers from the Autonomous Technological Institute of Mexico (ITAM), has developed a wireless technology that transmits data in visible light emitted from LED lamps, while lighting the room at the same time.

"Smart glass" iris could bring greater quality and flexibility to smartphone cameras

In a conventional camera lens, the iris consists of a set of overlapping mechanical blades that control the amount of light entering the camera. As efficient as this mechanical system is, it is too bulky and too difficult to miniaturize to be incorporated in smartphones and other compact devices. To address this, a team of researchers has used "smart glass" to create a micro-sized electronic iris that may bring much greater image quality and flexibility to smartphone cameras. Read More

Exoplanet-hunter SPHERE achieves first light

A new scientific instrument for detecting and observing remote exoplanets has been successfully installed on Unit 3 of the ESO's Very Large Telescope (VLT). The Spectro-Polarimetric High-contrast Exoplanet REsearch instrument, or SPHERE, recently returned its first set of images and is promised to revolutionize the exploration and study of these distant celestial bodies.

WORM display lets you write with light

Scientists at Universiti Malaysia Pahang (UMP) have developed displays that can be written on and erased with light. The WORM (Write Once Read Many) display is an optical storage device whose molecular geometry can be altered by shining light on it, allowing information in the form of words or pictures to be impressed on it in as little as 20 seconds. The environmentally-friendly display is also easy to dispose of, the researchers report, as users only have to scratch its surface to remove its protective coating and dip it in water to dissolve it.
