Automotive optoelectronics deals with application of electronic system and devices in automobiles, which use, detect and control light. Optoelectronics is increasingly being used in modern cars for advanced automated services. Automated headlights for better visibility, automatic brakes for higher safety, advanced driving assistance systems, night vision systems and active or passive infrared systems are some of the major applications of automotive optoelectronics in automobiles. The major components of automotive optoelectronics are infrared emitters, photo detectors, LEDs, solid state relays, optical interrupters and ambient light sensors. Infrared emitters are used in night time illumination for heads-up displays, occupant sensing arrays, driver assist systems and rain sensors. Ambient light sensors allows the headlights, backlights and other automotive systems to sense and respond to light just like a human eye. Optical interrupters are used for gear shift position sens...
