Dynamic measurement of explosion containment vessel deformation for explosive experiment is obtained using laser doppler effect. The system is based on optical heterodyning technologies, and uses half wave plate, quarter wave plate, polarization beam splitter and acousto-optic modulator to improve the intensity of doppler signal and signal-noise-ratio. Short time fourier transform and energy centrobaric correction method using hamming window is applied to improve the signal processing speed and the accuracy. The experimental results of explosive container are presented under 20g TNT explosion.
