Paper Abstract

The uniformity of the output of an integrated, quasi-linear array of bolometer elements is evaluated in terms of substrate temperature gradients, variations in bolometer thermal conductivity and temperature coefficient of resistance, and self-heating during readout. With a suitable offset compensation procedure, the array non-uniformity can be as low as a few parts per million of the DC offset voltage. Uniform substrate temperature changes as large as 10K can be tolerated.
