Paper Abstract

This paper presents the results given by the nominal design and tolerance analysis of a narrow-field-of-view camera lens equipped with a rotating prism scanning system. The first aspects taken into consideration have been the compensation of the chromatic aberration, distortion reduction, and the correlation between depth-of-field and lens resolution. Then, a rigorous approach to determine the relationship between the field-of-regard direction and the prism orientations is discussed. Finally, the tolerance analysis results give the predictable pointing direction precision as function of the system tolerances.
