Abstract

Optical remote sensing plays an important role in the study of planetary atmospheres, especially in determining trace gas abundance, temperature profiles and dynamics/winds. Instruments to be flown aboard interplanetary platforms must be small, have low mass and consume little power. Fabry- Perot interferometers (FPI) satisfy these physical constraints and are capable of acquiring spectra suitable for analysis of the atmospheric parameters. Two new applications of FPI technology have recently been developed at UM/SPRL: the multiplex Fabry-Perot interferometer (MFPI) and the multi-order etalon spectrometer (MOES). The MFPI produces a broad bandwidth high resolution spectrum via Fourier transformed interferograms produced by scanning the etalon over large distances. The MOES simultaneously measures several similar lines in a regular spectrum by matching its free spectral range to the line spacing. Thus MFPI provides a means for broadening the usable bandwidth and MOES can record improved signal-to-noise spectra at extremely high resolution. This paper reports recent progress in the design, construction and testing of a prototype instrument incorporating both the MFPI and the MOES concepts using a single set of etalon plates.
