The time when the bomb explodes is one of the most important indexes to appraise the test. 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 highcapacity, 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. |
