ABSTRACT:
The invention provides a viewing system which provides for a substantially continuous and unobstructed horizontal field of view over a desired viewing angle. The system comprises a plurality of entrance plane reflecting surfaces, each of which functions to reflect a field of view defined by an entrance aperture and a plurality of exit plane reflecting surfaces aligned with and spaced from each of said first reflecting surfaces for receiving a reflected view therefrom and for reflecting the view through an exit aperture to an observer. The entrance and exit reflecting surfaces are retained in fixed relationship. The number and width of said entrance apertures are such that the sum of all of the angles in azimuth subtended by all of the entrance apertures on a projected horizontal plane from a fixed reference point exceeds the angle in azimuth subtended by the system as a whole.
