Abstract

An alternative class of infrared projector real-time nonuniformity correction processor is introduced, based on the concept that the fundamental role of the processor is to reverse each of the projector processing steps as the input DAC voltage word is converted into infrared signal radiance output. The design is developed by assessment of the sequence of processes occurring within the projector and is tested by simulation. It is shown that there is potential for high fidelity nonuniformity correction across the infrared dynamic range without the need for the introduction of curve-fitting breakpoints.
