Displacement Sensor State Detection Method Based on Laser Interference

Abstract

One of the key techniques for accurate measurement of system response micro-thrust measurement technology, its measurement accuracy directly affects the final thrust measurement accuracy. The displacement sensor is a commonly used system response measuring device. In order to perform on-site detection of the displacement sensor's use state, and the laser interferometry measurement method is only related to the wavelength, the displacement sensor state detection method based on laser interference is proposed.
