OPTICAL-ELECTRONIC SENSORS WITH RETROREFLECTORS FOR CONTROL OF SPATIAL POSITION OF TURBINE ELEMENTS
Annotation
The way to improve optical-electronic sensors used for monitoring spatial position of elements of turbine units are considered. A scheme of sensor with two retroreflectors is proposed. The influence of sensor elements characteristics on the transformation of measuring data is analyzed. A correlation of the optical system characteristics with parameters and algorithms of the matrix photodetector is revealed. A physical model is developed based on optical-electronic sensor for monitoring object displacements was formed. Presented results of experimental studies confirm the formulated requirements for characteristics of sensors operating under workshop conditions.
