Design of Collection and Conditioning Circuit for a High Precision System of Photoelectric Velocity Measurement

Abstract:

In order to meet the requirements of high-speed projectile velocity measurement, design of a high-precision projectile velocity measurement device. Device adopts laser light source as detection target surface, receiving part adopts silicon cell array for photoelectric conversion. Silicon cell array using seamless splicing technology, eliminate the test blind spot. Design the sensitivity adjustable photoelectric conversion circuit, can effectively adjust the sensitivity of each pixel of the silicon photocell, effectively resolve the pixels sensitivity difference, reduce the jump poor in test, improve the projectile velocity measurement precision.
