ABSTRACT:
One or more holographic optical elements are placed within an aerodynamic front enclosure. Each element redirects a transmitted electro-magnetic wave to a radiation detector. The holographic optical elements correct by diffraction the aberration in a wavefront caused by transmission through the aerodynamic frontal enclosure. Each holographic optical element corrects for wavefronts coming from different directions.
