SPECTRAL OF PARTIALLY COHERENT LIGHT PASSING THROUGH AN APERTURE-LENS SEPARATION SYSTEM
部分相干光通过光阑-透镜分离系统的光谱特性

Starting from the propagation equation of partially coherent light,the spectral shift and spectral switch of partially coherent light assing through an aperture-lens separation system are studied.theoretical and numerical results show that the spectral shift and spectral switch of partially coherent light are mainly dependent on the coherence parameter,Fresnel number and the distance between aperture and lens.By a suitable choice of the system parameters,the position and number of the spectral is switch can be variable.
