摘要

The initial disturbance during rocket launching process is an important factor which affects the distribution of the rockets.Its measurement provides valuable information for theoretical aspects and engineering aspects. In this paper we present a 2-dimentional Position Sensitive Detector (PSD) angular movement parameter measurement system based on the optical lever principle. The usage of PSD for recording the change of optical point position can reduce the number of accessories, more over it improves the accuracy of signal processing and benefits real time processing.
