Abstract

Several years ago we invented a new type of Fourier-transform spectrometer using a shearing interferometer and a multichannel detector 1 ,2. Since this type of spectrometer contains no mechanically moving parts, it has many potential applications including a compact-size FTIR sensor for field-use and time-resolved spectroscopy of fast or transient phenomena. We have investigated several types of common-path interferometers with particular emphasis on easy optical alignment, durability, and ruggedness1-5. In this paper, we propose a new multichannel FTIR system with an extremely high optical throughput, which may prove optimal for field-use sensor applications.
