描述了一种用于有效地获得多色辐射器的综合信息的方法。在一定条件下，由衍射区的三维空间相干函数可以同时恢复辐射物体的空间和光谱细节。对象信息的恢复基于从基本公式[WolfE. CarterW. H、J.Opt.Soc.Am.68，953- 964（1978）]描述了场相关函数。提出了一种新型的干涉仪，用于空间相干数据的有效收集。实验结果的光谱图像恢复。
A method is described for efficiently obtaining the comprehensive information of a polychromatic radiator. Under certain conditions both the spatial and spectral details of the radiative object can be recovered simultaneously from the three-dimensional spatial coherence function in the diffraction region. The recovery of object information is based on a Fourier-transform relationship derived from the basic formula [ WolfE.CarterW. H., J. Opt. Soc. Am.68, 953– 964 ( 1978)] describing the field correlation function in terms of the source correlation function. A new type of interferometer is proposed for the efficient collection of the spatial coherence data. Experimental results of the spectral-image recovery are also presented.
