Optical

Abstract. An optical design concept is presented for a wide field of view camera, used to take pictures of a model board, which are displayed to the pilot of a simulated aircraft in real time. The concept achieves mapping functions and perspectives in three separate images that match the dis-play system properties over 140 deg field of view. This enables fast feedback of the model board images to the pilot by avoiding the need for computer correction of optical distortion. The geometry of the lens system also ensures good uniformity of brightness over the wide field of view. The provision of three axes of angular movement and computer optical design techniques are discussed. The general design and fabrication of a prototype is described. Subject terms: optical design; wide field of view; perspective; mapping functions; derotation prisms; optical alignment. Opt/ca/Engineering 31(11), 2434-2441 (November 1992).
