Abstract : Photoelectric infrared sensors are objects to the interference of sunlight and illumination light . Adop2ting average circuit ,optical and mechanical structure and the singe chip processor ,the problem is resolved ,Theca2 pability of anti2interference and measurement accuracy are improved obviously in non2contact rotation speed mea2 surement. The methods will have comprehensive use in speed governor and mechanical vibration displacement system.
Key words : photoelectric infrared sensor ; rotation speed ; measurement accuracy
