本文介绍了一种测量加色法电影印片机光阀跳光时间的新方法。它不需要过去那种经过印片、测密度、换算成时间的繁杂方法,而只需要通过八线示波器照相、冲洗后,立即可以读出跳光时间,而且测量精度可达几分之一毫秒。 This article describes a new method for measuring the light-up time of a light valve in a color-adding film printer. It does not require past the kind of printing, density measurement, conversion time complex method, but only through the eight-line oscilloscope photography, washing can immediately read the jump time, and the measurement accuracy of up to a fraction of a millisecond .
