Paper Abstract

The Department of Detectors of the Instituto de Astrofisica de Canarias, Spain is developing a data acquisition system (DAS) for an infrared camera based in a 256 X 256 InSb detector. The camera is going to work from 1 to 5 microns wavelength, with a scale on the sky of 0.5 arcsec per pixel, and will be installed as a common user instrument at the Carlos Sanchez Telescope in the Observatorio del Teide (Canary Island, Spain). A multiprocessor architecture has been chosen for the DAS, due to the very tight requirements on real time processing, and high speed storage capability (20 images per second readout rate, 2 images per second storage rate). The complete system is split into two main parts, the front end electronics and the user workstation. They are interconnected through an ETHERNET link.
