Contrast, spatial frequency, presentation time, moving velocity and phase reversal frequency of each grating are controlled independently.
每组光栅的对比度、空间频率、显示时间，移动速度和反相频率能单独控制。
In this paper, principle analysis shows that tricolor grating has the character of multi-wave superposed in spatial domain and separated in frequency domain.
通过原理分析说明，三色光栅具有的多光谱的空域复用、频域分离的结构特点。
The results indicated that the sensitivity is appoximately proportional to the square root of the length of grating. And so does the result derived from Fourier analysis and spatial-frequency channel.
从空间频率通道的观点出发，也可推导出对比灵敏度是和条纹长度的平方根成正比。
