Paper Abstract

The high spectral resolution capability of a Fabry-Perot spectrometer (FPS)1,2 has many unique applications. Although the basic theory is well established, a physically accurate end-to-end system model is much desired for understanding the capability of FPS-based systems. This paper describes the optical design of an infrared FPS along with a coherent beam propagation model of the FPS. Parameters that affect FPS signal-to-noise ratio such as FPS reflectivity, absorption, scattering and surface flatness are analyzed. Results from the coherent beam model are compared with endto- end system performance model findings. System performance impact of background noise due to self-emission of the FPS is also discussed. A trade-off study between a single etalon and a double etalon FPS is discussed.
