摘要

A high-speed passive FT-IR imaging spectrometer has been designed and built. This sensor, based on the patented Turbo FT interferometer from D&P Instruments, was developed under contract with the U.S. Army Edgewood Chemical and Biological Center (ECBC) in Aberdeen, MD. The Turbo FT is a rotary high speed Fourier Transform Infra-Red (FT-IR) spectrometer which has been previously run at speeds up to 360 scans per second, at up to 1 cm~(-1) resolution. It has also operated in rugged environments, including helicopter and fixed wing platforms. This sensor was run at 8 cm~(-1) resolution and 30 scans per second with an 8X8 (64 element) LWIR (8-12 micron) mosaic detector. An on-board auto-calibrating blackbody accessory was built in, and automated chemical detection software was developed. These features allow in-flight calibration, and facilitate remote detection of target gas clouds. This paper will discuss the system specifications, preliminary sensor performance, and results from initial testing.
