Abstract

The AVIRIS instrument has a separate dedicated analog signal processing chain for each of its four spectrometers. The signal chains amplify low-level focal-plane line array signals (5-10 mV full-scale span) in the presence of larger multiplexing signals (- 150 mV) providing the data handling system a ten-bit digital word (for each spectrometer) each 1.3 ps. This signal chain provides automatic correction for the line array dark signal nonuniformity (which can approach the full-scale signal span).
