Abstract: Systems and methods are disclosed for improving image quality by modifying received radiation wavefronts with one or more uncalibrated variable phase plates at the pupil plane of the optical system, to produce an atmospheric-like blurred image on the focal plane with an effective increase in the sampling parameter Q. Real-time image restoration algorithms may then be applied to data sets sampled from the blurred image formed on the detector array. Numerous phase plate embodiments are provided for modifying the wavefront.

Abstract: A multi-axis self-contained sensor system includes an outer spherical housing and an inner spherical housing. The outer spherical housing has a transparent spherical shell that surrounds a first cavity and having a first refractive index (RI). The inner spherical housing is in the first cavity and is completely surrounded by the outer spherical housing. The inner spherical housing has a first average density and includes a spherical wall that surrounds a second cavity. A sensor system is contained in the second cavity, and a suspending fluid layer is interposed between the outer spherical housing and the inner spherical housing. The suspending fluid layer is composed of a fluid having a second RI.
