A design of a variable interference filter imaging spectrometer (VIFIS) system is described. A set of systematic concepts, including continuous spectral image encoding using a spatially variable light-frequency-selective principle; spectral image data reconstruction using a transputer co-processed video rate pushbroom queue processing algorithm; and complete spectral image information storages and retrieval using video recording, have been adopted in the system. These result in a system that can supply up to 640 spectral bands of 8-bit images within the spectral range from 400 to 700 nm after one flyby. Many other attributes such as compactness of the sensor, simplicity in operation, availability of in-flight image inspection, accessibility in flight height and velocity are other advantages of the system. A preliminary test over the Tay Estuary was performed aboard a Cessna 152 aircraft. The images and spectral profiles obtained show the system to be an effective tool for remote sensing. 10 refs.
