We have previously reported on the conceptual design and predicted performance of a new type of dedicated astronomical telescope to be used for a deep photometric survey for galactic and extragalactic variability and polarization.' Data derived from this survey will be useful for a wide variety of astronomical investigations including the definition of

Most of the laser speckle methods utilize subjective speckles in that speckles are recorded through a lens whose aperture determines the admitted spatial frequencies. Objective speckles are those intrinsically formed by the scattering wavelets. In this paper we propose the use of far-field objective speckles generated from a ground glass to measure ...

Design Of Null Lens Correctors For The Testing Of Astronomical NnfitÃÂââÃÂìÃÂÃÂC
Optical Engineering, 1988Some design examples are presented that illustrate the design of null correctors for the testing of strong aspherical surfaces such as those that are of interest in astronomical instrumentation. The design and analysis of an Offner corrector for an f/1 paraboloid is given.
