Abstract

Resistor array infrared projectors offer the unique potential of simultaneously covering both a wide apparent temperature range and providing fine temperature resolution at low output levels. The temperature resolution capability may not be realized, however, if the projector error sources are not controlled; for example, residual nonuniformity after nonuniformity correction (NUC) procedures have been applied, temporal noise in analog drive voltages and quantization at several points in the projection system, all of which may introduce errors larger than the desired resolution. In this paper the temperature resolution limits are assessed in general. In particular, the quantization errors are assessed and the post-NUC residual nonuniformity levels required for achievement of fine temperature resolution are calculated.
