Differential Absorption Sensors : The Elimination Of Led Temperature And Ageing Effects
Evangelos Theocharous · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1987
A new technique has been developed which is capable of eliminating the effects of temperature, age, or any other parameter which can change the LED emission spectrum, from differential absorption sensors. This method was verified experimentally using a GaAs differential absorption temperature sensor.
