Abstract

Tests for modulation transfer function (MTF), particularly for staring systems, are affected by the position of the test target with respect to the rows and columns of the detector array. To alleviate the position-dependent nature of the measurement, we have developed a target that uses random patterns of known spatial-frequency content. In this way a phase-averaged MTF is measured, which is indicative of field performance on natural scenes.
