According to the principles concerned with explosion radiation  the principle of measuring the time of remote explosion point and composition of measuring system is introduced. Use CCD to record the explosion radiation  DSP to process and record the high-capacity  high-speed video signals  and convert the exploding process examined by floating amplifier into digital signals. Besides  the article analyzes the composing and structural design of the log's optical system  principle of electric control and floating amplifier  dynamic range of the system  power analysis of the incident light  and how to improve the accuracy of measurement in great detail.
