Paper Abstract

The capability of a conventional inertial adaptive optical system in compensating for thermal distortion is examined. Since thermal irradiance mapping is a process that transfers anomalies in intensity to aberrations in phase, adaptive optics are particularly useful. Both linear spatial filtering and variance minimization methods of analysis will be discussed. The linear spatial filtering concept will be applied to the specific problem of thermal irradiance mapping and shown to be equivalent, within the system constraints, to a least-squares fit of the deformable mirror surface to the wavefront. The special cases of Gaussian beams, annular beams, and irradiance profiles which can be expanded into Zernike polynomials will be studied in detail.
