CU Boulder researchers have built high-performing optical microresonators, opening the door for new sensor technologies. At ...

This post sponsored by Texas Instruments. The OPT3001 sensor accurately measures the intensity of light visible to the human eye regardless of light source. Its precision spectral response tightly ...

With the TSL2550 sensor, the intensity of ambient light can be converted to digital signals that, in turn, can be used to control the backlighting of display screens found in portable equipment, such ...

Shine a flashlight into a murky pond water and the beam won't penetrate very far. Absorption and scattering rapidly diminishes the intensity of the light beam, which loses a fixed percentage of energy ...

Researchers at Tor Vergata University of Rome have developed a biohybrid image sensor that mimics how the animal retina ...

The ambient light sensor on your Dell business laptop adjusts the brightness of your screen according to light intensity picked up from the room. In a brightly lit office, the ALS increases the ...

ALSs (ambient-light sensors) have been around for years, but they are now seeing increased use due to the success of smartphones, such as Apple’s iPhone. The iPhone uses an ALS to reduce power demands ...

AND THEN THERE WAS LIGHT. Well, the whole electromagnetic (EM) spectrum, actually. Visible light occupies only a small portion of the spectrum, which extends from below the extremely low frequency ...
