| The flash intensity is one of the important index of all kinds of bombs during the explosion time, it has great significance for measuring the flash intensity. This paper designed a wide range, high-precision flash intensity measuring system in order to meet the measurement requirements.This system use a high sensitivity, high linearity photodiode as the metering probe through which the flash intensity data can be collected during the explosion time; this system use a high-precision amplifier as the signal processing circuit; this system use a high precision A/D converter as the signal quantization circuit; this system also use a high-speed microcontroller as the central processing unit in order to achieve the high-speed processing goal; this system also use the standard USB interface as the communication transmission module in order to ensure the high-speed data transmission; and this system also use the Virtual Instruments as the man-machine interface in order to observe the signal data. |
