摘要
针对大面积反射式光幕靶的特点设计了光电转换电路,并通过野外试验对测试电路的性能进行了实弹考核。该光电转换电路具有低噪声、高增益、低输出阻抗、较好的响应带宽和带负载能力。通过野外实弹试验表明,该电路能有效去除飞虫干扰和杂散光的干扰,保证了大面积反射式光幕靶的测试性能。
A photo-electric conversion circuit was designed based on characteristics of large area reflection-type light screen target, and analog calibrator was used to check performance of the circuit. By testing, the photo-electric conversion cir- cuit has merits such as low noise, high gain, low output impedance, good response bandwidth and abilities of driving load. Furthermore, the live fire test shows that the circuit can reduce the interference of flies and stray light effectively, which ensures the target＇s performance.
