Abstract
The design for a telescope is presented which calls for small optical components in an all-reflective wide-field-of-view phased-array configuration. Attention is given to the geometric phasing conditions and other phasing requirements for the phased-array design, and analytical expressions are set forth for the paraxial relations and distortion. The design of the subtelescopes is based on a three-mirror design, and particular attention is given to the problem of subtelescope field curvature. It is shown that several configurations provide the required corrections for the field curvature and the stigmatic aberrations. Subtelescope aberrations such as coma can affect optical phasing, which indicates that a tolerance analysis conducted aberration-by-aberration is necessary for developing the all-reflective configuration.
