EVALUATION OF PARABOLIC OPTICS FOR THE AEROSPACE LAMELLAR GRATING INTERFEROMETER.

Abstract

The Czerny-Turner collimating system used in the Aerospace lamellar grating interferometer is shown to lead to significant instrumental line broadening. This system is compared with an off-axis parabolic mirror system, and the following conclusions are reached. (1) The instrumental line broadening of the parabolic mirror system will be an order of magnitude smaller than for the Czerny-Turner system. (2) The coma of the parabolic mirror system is negligible. (3) The wavefront distortion of the parabolic mirror system is less than that of the Czerny-Turner system. (Author)
