Paper Abstract

Conventional thermal images which use single-element detectors usually incorporate mechanical scanning systems which move the detector's instantaneous field of view in a regular pattern to cover the imager field of view. Alternative techniques are possible which utilize discrete reticle masks to multiplex several resolution elements onto the same detector in order to increase the total measurement time per resolution element. Benefits and limitations of these techniques are discussed.
