Paper Abstract

Resistor array infrared projector nonuniformity correction (NUC) is currently limited in fidelity. In the flood technique a fundamental limitation has been the inevitable presence of Moire fringes. In this paper, an advanced NUC procedure is described in which the Moire patterns are successfully subtracted, leading to improved levels of residual nonuniformity. It is shown that, irrespective of the projection technology, the Moire fringes exist at the unit-under-test image plane where they appear in general as sampling noise. Their control through choice of mapping ratio is discussed.
