本文提出了一种高精度,高稳定度、高频率时标发生器的方案。由于采用磷砷化镓(GaAsP)固体发光管作为脉冲光源,石英晶体振荡器经分频后的脉冲信号作为驱动信号源,因而与现有的时标发生器方案比较,它具有体积小,重量轻,抗振性好,驱动功率小,发光波长与胶片感光灵敏度的一致性好,时标频率高(已达30千赫/秒),稳定度好等优点。它是专门为狭缝式高速摄影机设计的,对于其他同步相机也具有很大的实用意义。
This paper presents a high-precision, high stability, high frequency timing generator program. As the use of GaAsP solid-state light-emitting tube as a pulsed light source, the quartz crystal oscillator pulse signal after the division as the drive signal source, and therefore compared with the existing time-scale generator program, it has a small size, weight Light, good vibration resistance, low driving power, good coincidence of light-emitting wavelength and film sensitivity, high frequency of time scale (up to 30 kHz / sec) and good stability. It is designed for slot-speed high-speed camera design, for other synchronous camera also has great practical significance.
