Firstly, the structure of the laseraccelerometer based on PSD are designed in this dissertation. The relation between the output pulse difference and the input acceleration is derived.
An accelerometer shock dynamic calibration method with a grating laser interference technique is described, and the differential acceleration evaluation is specially discussed.
