The eye's light-sensing retina taps different circuits depending on whether it is generating image-forming vision or carrying out a non-vision function such as regulating pupil size or sleep/wake ...

Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have created the world's first all-integrated sensor circuit based on ...

By harnessing the unique properties of tantala (tantalum pentoxide), a team of US-based researchers has created a photonic integrated circuit that can be tuned to deliver laser light across a broad ...

To see under starlight and moonlight, the retina of the eye changes both the software and hardware of its light-sensing cells to create a kind of night vision. Retinal circuits that were thought to be ...

Engineers at Rice University have developed a dual-bacterial system that converts chemical signals directly ...

Texas Advanced Optoelectronic Solutions (TAOS) has introduced two light-to-digital converters to simplify the design and deployment of ambient light sensing in display panel products. The patented, ...

A research team led by Pasquale Scarlino at EPFL has built a small, tunable detector capable of sensing individual microwave photons and converting them into measurable electrical current. The device ...

Adding an ambient light sensor to portable devices such as tablets, smartphones, and laptops extends battery life and enables easy-to-view displays that are optimized to the environment. This ...

Simply stated, ambient light sensing (ALS) is the ability to measure the brightness of light incident on a surface. It is often useful to utilize this brightness information to control certain aspects ...
