摘　　要：介绍了一套基于光度探头、ADuC 812开发板和PC机,用以测定闪光灯的特性曲线,能够满足一般闪光灯测试要求的实验系统。提出了一种在有限采样速度条件下,以硬件判断获取瞬时信号的方法。按照此系统的设计方法,只要采用模数转换速度足够高的AD器件,就可以实现对大多数闪光灯特性曲线的获取。An experiment system based on ADuC812 development board and PC computer,sufficient for the measurements of characteristic curves of common flash lamps,is introduced. A method to acquire the instant signal by hardware judgement, under a finite sampling rate, is proposed. The system can measure characteristic curves of most flash lamps as long as an AD device with sufficient speed is employed.
