Abstract
An imaging device for processing an optical image in the visible and/or infra-red wavelength bands. An optical image receiving area is divided into four segments and each segment is associated with an optical sensing means in the form of a semiconductor chip comprising a plurality of pixels. Each segment also includes a reflection means for reflecting the particular optical image to the associated optical sensing means. The reflecting means preferably takes the form of a reflecting surface within a cube comprising two prisms. The reflecting surface may be fully reflecting dichroic or holographic. A further optical sensing means in the form of a semiconductor chip is employed to the rear of the image receiving areas and is positioned to sense for small separate segments of the four guarter segments in the center of the overall optical image. All the separate received optical images are processed electronically to produce a composite image.
