基于闪烁光度法, 设计并搭建了一种新的测量人眼视见函数的实验系统, 得到了人眼视见函数曲线。利用人眼对间断光的响应特性, 有效地避开了白光和单色光的颜色差异对亮度的干扰, 通过对比两束光视亮度的方式, 使系统达到光度平衡, 进而度量辐亮度得到人眼视见函数曲线, 并与CIE推荐的标准视见函数进行差异比较, 分析了差异原因和改进方法, 从而深入了解光电探测器的光响应与人眼的差异, 为今后的新型光电探测器的研究与应用打下基础。结果表明, 实验系统可用于测量人眼视见函数, 与CIE推荐的标准视见函数曲线吻合程度较高。

Based on the flicker photometry, the new system measuring the visual function is designed and set up. The visual function curve is acquired finally. The interference of different colors caused by white light and monochromatic light is avoided according to the response characteristic of eye to discontinuous light. By the method of comparing visual brightness, the photometric equilibrium of the system is reached, and radiation quantities are measured to obtain the visual function curve. The difference between the experimental measurements and the CIE recommended values of V(λ) are analyzed and improving solution is proposed. The difference is better understood between light response of photoelectric detector and human eye. A foundation is laid for the application of new photoelectric detector in the future. The results show that the system is capable of measuring the human visual function, and the degree of overlap between the CIE recommended standard visual function curve and the visual function curve measured in the system is promising.
