Analysis of Parameters of Optical Linear Displacement Transducer with Open Channel
This article describes the structure and principle of operation of the optical linear displacement sensor with open optical channel. Scope of application in industrial equipment for measuring vibration parameters is determined. Analysis of errors caused by external illumination of the optical channel and a change in the reflection coefficient of the object surface is accomplished. Methods of reducing errors are considered. Recommendations about the use of transducer as part of information and measurement systems are provided.
