Abstract

This paper attempts to explore the feasibility of a system based on laser Doppler technique which has been established to realize remote dynamic measurement of high velocity deformation parameters of explosion vessel. It aims at developing a stable and reliable non-contact instrument with high precision for the measuring of explosion on site. Doppler signal's SNR is very low in remote measurement of explosion vessel, a moving solid object with high velocity. To enhance signal intensity, restrain noise and extract weak Doppler signal is the key to realizing remote measurement with high precision. Both optical structure optimizing and digital signal processing used to solve the arduous problem above will be discussed in this paper. The test results prove that the relative error of the instrument is less than 1% in measuring displacement.
