ABSTRACT:
A phased array telescope in which the output field angle of each afocal subtelescope is equal to the arcsin of the product of the magnification and the sine of the input field angle. The resultant subtelescope distortion reduces piston error at the input to the beam combining telescope to increase resolution by reducing piston error otherwise caused by distortion-free subtelescopes. The phased array telescope uses only reflecting surfaces in order to operate over a wide spectral band. Optically powered primary, secondary and tertiary reflecting surfaces are combined with an aspheric folding mirror before the image that would have been formed by the secondary mirror to control the distortion of each subtelescope to exactly follow the arcsin rule provided.
