摘要
三色光栅是一种特殊的空间光调制器。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。介绍了它在以白光信息处理为基础的信息技术领域如彩色摄影、白光彩色相关识别、多通道光谱段摄影等方面的应用研究状况 ;指出基于三色光栅思想还可以构造出各种各样的多色光栅器件 ,具有更广泛的应用前景。
Tricolor grating is a new type of spatial light modulator.In this paper,principle analysis shows that tricolor grating has the character of multi-wave superposed in spatial domain and separated in frequency domain.Its applications in the field of information technology are introduced,such as color photography,white-light color joint transform correlator,multichannel spectra photography,etc.It is point out that many other kinds of multicolor gratings can be fabricated from tricolor grating and will be applied further in the future.
