根据 LCD 显示器亮度的均匀性和显示光栅对比度的稳定性实验分析，提出了一种采用 LCD 显示器显示光栅测量人眼对比度敏感视觉特性的实验方法，并测量了48位青年对象对3种平均亮度光栅的对比度视觉特性，且与目前有代表性的测量方法和结果进行了对比分析。结果表明该测量方法是一种有效、实用和简便易行的人眼对比度敏感视觉特性测量方法。
According to the experiments analysis about the uniformity of luminance and stability of contrast of grating displayed on LCD display,a method is proposed to measure contrast sensitivity characteristics of human visual system by displaying the grating using LCD.The contrast sensitivity characteristics of 48 youngers who detect gratings with three kinds of luminance were measured,and it is compared with the typical measurement methods and results.The results show that the measur-ing method is effective,practical,simple and easy to measure the contrast sensitivity characteristics of human visual system.
