介质折射率对部分相干光透射谱的影响

研究了部分相干光通过均匀介质薄片后的远场透射谱，分析了介质折射率对GSM光束的远场透射谱的影响，并作了数值计算.结果表明透射介质的折射率对远场透射谱频移和频谱分布均产生很大影响.

Effect of Refractive Index of Media on the Transmitted Spectrum of Partially Coherent Light

The far-zone spectrum of partially coherent light transmitted from a homogeneous medium are studied. The effects of refractive index of medium on the far-zone shectrum in the axial and paraxial points are analyzed in detail for the case that Gaussian Schell-model (GSM) beam transmitted from various dielectric slabs. Results of numerical calculations show that the refractive index of transmitted medium has strong influnce on the spectral shifts and the spectral distributions of transmitted spectrum in tne far zone.
