人眼调制传递函数自动测试装置

本文介绍一个用单片机控制的人眼视网膜－大脑系统调制传递函数测量装置，与传统方法不同，该装置调制对比度是利用电光晶体控制激光束强度的来达到的。该装置不但可以测量空间调制传递的函数，还可测量时－空调制传递函数，并以数据和曲线的形式打印输出。

An apparatus for automatic measurement of modulation transfer function of human eyes

A single-chip computer controlling system for measuring the modulation transfer function Of human retina-brain visual system is presented.Unlike the conventional method, the system uses an ele ctrooptical crystal to control the intensity of laser to achieve the change of modulation of the grating. The system allows both spatial MTF and temporal MTF measurement. The measurement is controlled by a single-chip computer and the measured data and curves are printed out.
