Influence of Seidel distortion on combining beams from a phased telescope array.

摘要: When beams from an array of afocal telescopes are presented to a beam-combining telescope, tilt errors the beam wave fronts with respect combined front place limits on achievable field view (FOV); these limits, best our knowledge, have not previously been correctly described in literature. We show that if front-end just right Seidel distortion coefficient, then error does limit FOV. If this is case, at least small FOV’s can still be obtained, even FOV centered on-axis direction.
