A diffractive optical element is interposed between the exit beams from a ring laser gyro readout and the photodetectors for detecting such beams. The diffractive optical element permits the use of photodetectors much reduced in size in order to minimize gyro performance degradation due to radiation.

Radiation-hardened RLG readout

A head mounted display to view a created image and an external scene includes a display displaying the image and a prism receiving the image which includes a first surface for diffracting the image, and a second and third surface reflecting the image to a user of the head mounted display.

High brightness see-through head-mounted display

A three-axis attitude orientation system for a spacecraft is described. The single sensor provides roll and pitch information by locating the centroid of the earth and using this as a reference point. The system determines yaw by tracking the position of stars which appear in the field of view around the earth. Three-axis attitude is determined through ultraviolet imaging of the earth's limb and adjacent stars. A diffractive optics sensor and intensified CCD array are utilized for this purpose.

Wide field of view sensor with diffractive optic corrector

A head mounted display having an image source, an optical relay system and a combiner for producing an image from the image source to the eye of a pilot in which the optical system includes at least one diffractive surface to compensate for aberrations and distortions in the display.

Head mounted display utilizing diffractive optical elements

A three axis attitude orientation system for a spacecraft in orbit which employs a single UV sensor. The single sensor provides roll and pitch information by locating the centroid of the earth and using this as a reference point. The system determines yaw by tracking the position of stars which appear in the field of view around the earth. three axis attitude is determined through ultraviolet imaging of the earth's limb and adjacent stars. A non-conventional wide angle optics assembly and intensified CCD array are utilized for this purpose.

Apparatus for determining 3-axis space craft attitude

A helmet mounted display utilizing a pair of image sources mounted low on the helmet of a pilot and projecting an image across in front of the pilot's face to the opposite partly reflecting portions of the visor of the helmet to create an image for each of the pilot's eyes, which image is combined with the scene being viewed through the visor by the pilot.
