异色调制测光是一种方法，在该方法中，呈现一系列固定的标准亮度/测试亮度比，并且在每个比率下，该对的调制深度被同时减小，直到观察者报告闪烁消失为止。期望是在表示亮度匹配的标准/测试比率下的明显的最小调制灵敏度。在其他亮度比下，闪烁灵敏度应随标准和测试之间的亮度差异而变化。我们设计了理论模板来描述调制灵敏度作为标准/测试比的函数。其他闪变研究的结果表明，闪变灵敏度预计将落在线性系统(灵敏度与调制幅度成正比)和韦伯系统(灵敏度与调制百分比成正比)之间。使用“红”和“绿”光，在低明度亮度下，这一期望得到了很好的实现。在更高的亮度下，当“红色”光的亮度高于“绿色”光时，观察者对调制的敏感度比模型预测的要低得多。
Heterochromatic modulation photometry is a method in which a series of fixed standard luminance/test luminance ratios are presented, and at each ratio the modulation depth of the pair is reduced in tandem until the observer reports that flicker disappears. The expectation is a distinct minimum modulation sensitivity at the standard/test ratio representing the luminance match. At other luminance ratios, flicker sensitivity should vary with the luminance difference between standard and test. We have devised theoretical templates to describe modulation sensitivity as a function of standard/test ratio. The results of other flicker studies indicate that flicker sensitivity would be expected to fall within the domain between a linear system (sensitivity proportional to the amplitude of modulation) and a Weberian system (sensitivity proportional to percent modulation). Using ‘red’ and ‘green’ lights, at low photopic luminances this expectation is well realized. At higher luminances and when the ‘red’ light is of higher luminance than the ‘green’, observers are much less sensitive to modulation than the models predict.
