Abstract—Reflective color sensing is typically realized through pho- todiodes with multiple illuminants or photodiodes coated with color filters containing a single illuminant. This paper presents the ...

Allowing users to detect color differences in liquids or solids, the company's reflective sensor assembly combines a white LED with a reflective color-sensor chip in a miniature plastic housing ...

The body hairs of the Saharan silver ant cause total internal reflection of light to make the ants almost ten times more reflective, preventing overheating and yielding their silver sheen, according ...

Liquid metal controlled by low voltage reversibly switches color and infrared response in nanoscale surfaces, enabling low power reflective displays, sensors, and optical security features. (Nanowerk ...
