Abstract
AGA System 680 (2-5 µm) and 680 LW (8-13 µm) thermovision cameras have been interfaced to a high speed ADC and pulse code modulation recording system. The data acquisition system continuously collects the digitised output from both AGA linescan cameras, each at 209 Kwords/s, with a dynamic range of 60 dB for periods up to 15 minutes (tape reel size limited). The data is subsequently recovered from tape under minicomputer control at low replay speeds, converted into a frame sized block format, and dumped onto digital magnetic tape for further computer analysis. A range of peripheral devices, including a colour graphics system, provide facilities for off-line data processing, frame storage and display. Quantitative field of view measurements have been made using high intensity quartz halogen bulbs and the instruments have been radiometrically calibrated against reference black bodies in wave bands defined by interference filters.
