摘要
本文介绍一种能同时测量视觉系统时－空调制传递函数的装置，它是在激光干涉法视网膜调制传递函数测定装置上增加条纹闪烁机构而成。其测量范围为：视力０．１～１．５；调制传递函数３～１００；时间频率（ｆ）０．５～１６Ｈｚ。视力和调制传递函数按几何级数分为１３档。
n apparatus capable of measuring simultanously spatialtemporal modulation transfer function of human visual system was introduced. The apparatus was made by cooperating laser MTF measuring apparatus with a device to flick interference frings of MTF apparatus. The measuring ranges of the apparatus were 0.1￣1.5 for IVA, 3100 for MTF, and 0.5￣16Hz for temporal frequency. There were 13,13, and 6 grades separated according to geometric series for IVA, MTF, and temporal frequency respectively.
