The optical system used by Kandpal, Vaishya, and Joshi in their experiments on coherence-induced spectral shifts is analyzed theoretically. An approximate form for the cross-spectral density in the secondary source plane is obtained, and it is shown that, contrary to the assertions of Kandpal, Vaishya, and Joshi, the corresponding complex degree of spectral coherence in this plane is wavelength dependent. After making some assumptions about the behavior of the interference filter used in the system, an approximate form for the spectrum of the light on-axis in the observation plane is obtained. It is shown that the peak wavelengths of this spectrum do not agree with those reported by Kandpal, Vaishya, and Joshi. Possible reasons for this disagreement arc discussed.
对坎德帕尔、瓦伊希亚和乔希在其关于相干诱导光谱频移的实验中所使用的光学系统进行了理论分析。得到了二次源平面中互谱密度的近似形式,并且表明,与坎德帕尔、瓦伊希亚和乔希的断言相反,该平面中相应的光谱相干复度与波长有关。在对系统中所使用的干涉滤光片的行为做出一些假设之后,得到了观测平面中轴上光的光谱的近似形式。结果表明,该光谱的峰值波长与坎德帕尔、瓦伊希亚和乔希所报告的波长不一致。讨论了这种不一致的可能原因。
