Abstract
This paper uses the combination of laser heterodyne technology with linear frequency modulation technology to load thickness of plate glass to the heterodyne signal frequency. By researching on the theoretical models of heterodyne signal for measuring thickness of plate glass, the direct intensity detection can be replaced by heterodyne signal frequency detection and the effects of light source power stability and environmental perturbation can be removed. The measuring accuracy of electrostriction coefficient can be further improved by using the frequency demodulation to obtain thickness of plate glass. This method is used to measure the thickness of plate glass, and simulation results show that the maximum relative measurement error is 0.01 %.
