Michelson spectrometer
WebFor the ordinary Michelson interferometer the term in sin 2 i dominates, which is the same as for the Fabry–Perot spectrometer when the term (1 − cos θ is approximated. This is why these devices have quadratic angular dispersion. With dispersion of fourth order, the optical path difference changes very slowly with angle. WebIn the mid-1880s Albert Michelson developed an interferometer, which uses a semi …

Web2 days ago · 1.Introduction. The Michelson interferometer and its many variants are the foundation of many optical and non-optical spectrometry designs. One particular type is the Fourier transform spectrometer [1].It uses a moving mirror in one of the arms of Michelson interferometer to generate interference signals and uses a single pixel photodetector to … WebDec 8, 2024 · You can use a spectrometer for very short coherence but you need a very high Q system for long coherence, so that would be a Michelson or an Echelon. The most precise systems of this kind that were ever built are probably the …

The investigated electromagnetic radiation (most frequently, infrared light) is sent to an interferometer, normally in the form of a Michelson interferometer.One then measures the optical power at the output of the interferometer as a function of the …
WebAn InGaAs detector was used with a Nicolet 6700 spectrometer containing a Michelson interferometer; light entered from a scope attached to the roof. Data collection was limited by malfunctions of the third party software which controls the spectrometer, poor weather conditions, limited ability to align the spectrometer, and the condition of the Web张淳民，博士，教授，博士生导师。西安交通大学空间光学研究所所长，国家基金委信息学部第十一、十二届专家委员会成员。美国光学学会（osa）会员，中国光学学会理事，中国光学学会空间光学专业委员会副主任，陕西省光学学会副理事长，全国高校电磁学研究会副理事长，全国高校光学研究会 ...
