We present here a technique for modulating contrast in gratings seen in Maxwellian-view or on a projection screen. The method can be used with achromatic or chromatic grating stimuli. It is based on a high frequency oscillatory displacement of the grating image, which in turn produces a smearing of the image on the observer's retina. The waveform of the displacement and its amplitude determine the appearance and contrast of the image produced on the retina.
我们在此介绍一种用于调节在麦克斯韦观察法中或投影屏幕上看到的光栅对比度的技术。该方法可用于消色差或彩色光栅刺激。它基于光栅图像的高频振荡位移，这反过来又会在观察者的视网膜上产生图像模糊。位移的波形及其幅度决定了在视网膜上产生的图像的外观和对比度。
