Light therapy is one of the oldest modalities used to treat a variety of health conditions. The use of coherent light sources (like lasers) and non-coherent light sources (like light emitting diodes ...
Scientists have discovered a potentially promising infrared LED and infrared detector component. This compound -- composed of calcium, silicon and oxygen -- is cheap to produce and non-toxic. Many of ...
Proximity sensing based on infrared signal acquisition and processing typically requires two parts to form the optical front end: an infrared LED and an optical sensor. The infrared LED beams infrared ...
