A kind of adaptive control optical power meter system is put forward

which uses the method of circuit design combining with program control algorithm to make laser emission power plan for adaptive control laster

and digital potentiometer is used to adjust drive current to simulate algorithm current change caused by atmospheric channel parameter variation

the system can adaptively adjust transmitting power with the change of atmospheric channel parameters

in order to ensure the quality of communication.In experiment

Agilent 8163B optical power meter is used as standard through comparative analysis

linearity of adaptive optical power control is better

relative measurement error is less than 1 %

stability is 5 % higher than that of Agilent 8163B optical power meter.
