Miniaturization of optical spectrometers pdf
WebHere, in a very simple form, is a schematic of a spectrometer. First, we have a light source. Second, we have some sort of device that can select a specific wavelength for that light. … WebThe diffraction at mirror facets restricts the size of step mirrors for static step-mirror-based Fourier transform spectrometers. This paper discusses the miniaturization of these step mirrors and proposes a quasiperiodic approximation of Fresnel diffraction to analyze the diffraction effect.
