A system for image-plane holography that uses a spectrally and spatially broad radiation source is analyzed and shown to provide depth discrimination in excess of that offered by conventional confocal imaging. The enhanced depth discrimination is a consequence of two factors: the simultaneous reduction of both the spatial and the temporal coherence of the source, and the special property of certain grating interferometers of presenting a spectrally dispersed light beam to the object while forming achromatic fringes at the hologram-recording plane.
一种用于像平面全息术的系统，该系统使用光谱和空间上均宽频的辐射源，经分析表明其深度分辨能力超过传统共焦成像。深度分辨能力的增强源于两个因素：一是源的空间和时间相干性同时降低；二是某些光栅干涉仪的特殊性质，即在全息记录平面形成消色差条纹的同时，向物体呈现光谱分散的光束。
