Abstract
In Direct Write Scene Generation (DWSG) a critical lens design parameter is the optical crosstalk, or the undesired energy incident on adjacent pixels (EOAD). Crosstalk must be minimized to obtain the proper scene projection fidelity. The laser scan lens systems used in this scene generation technique are typical f(theta) and can be optimized by adjusting the diameter of the input gaussian beam in relation to the entrance pupil. The optimum gaussian beam diameter is dependent on the resolution requirements placed on a system and the test article metrics. Optical cross talk calculations are used to gauge the performance of systems with square and circular entrance pupils. This paper will address the calculated relationship between crosstalk and the truncation of the Gaussian input beam.
