專利摘要

The present invention relates to a photoelectrical feedback sensing system. A first light signal passes through the sensing apparatus. A second light signal corresponding to a characteristic of a sample within the sensing apparatus is outputted from the sensing apparatus. The first photo detector recevices the first light signal and outputs a first eletric signal corresponding

to the intensity of the first light signal .The second photooutputs a second electric signal corresponding

to the intensity of the second light signal.A driving sinal is generated by the micro-processor to drive the light-emitting unit.The micro-processor revice the second electric signal and converts the second electric signal into a digital signal. The feedback circuit modulates the driving signal for maintaining the optical stability  of the first light signal so that the sensing system is less affected by environmental temperature fluctuation and noise interferences.
