- 論文の詳細を見る
An interferometric spectrometer which delivers a spectral power in real time without Fourier transform calculations is described. In this spectrometer, an interferogram is generated by a two-beam interferometer as a spatially distributed pattern on an array detector. This array and a following electronic circuit construct a spatial band-pass filter which transmits a spectral component at a desired wave number. The wave number can be changed by moving a mirror in the interferometer. This spectrometer is handled as easily as a grating spectrometer, whereas the throughput advantage is retained. The emission spectra of a He–Ne laser and a low-pressure mercury lamp driven by AC current are measured to demonstrate the spectrometer performance.
