Numerical design analysis techniques for phased-array wide field-of-view imaging

摘要

Abstract: The process of simulating the optical performance of the phased array optical telescope has given us new insight on the role of the array and subaperture chief rays, array aberrations (global) and subaperture (individual telescopes) aberrations. The seven 3rd order Siedel surface aberration paraxial equations are reformulated in terms of phased array and includes a numerical example. In addition, a design method of combining each telescope chief ray to determine the vertex of the reference sphere is described. A theoretical calculation of subaperture piston resulting from array (global) 3rd order aberrations with numerical examples is presented.!17
