Abstract

A helmet-mounted system for display of complex video images projected to infinity with a miniature cathode-ray tube, an optical device for transferring the image from the tube to the focal surface of a spherical mirror, and a semi-reflecting plane mirror in the form of a thin film. The image projected to infinity by the spherical mirror which is utilized on the axis is reflected from the plane mirror while enabling the viewer to see his normal surroundings at the same time. The collimating unit is advantageously constituted by two juxtaposed and cemented prisms.
