A method of generating a holographically reconstructed image of a model oct so that the image will appear to have lamps of various predetermined colors at predetermined locations and having predetermined sectors of viewability in which color is generated from a laser light source having a coherent beam output comprising a plurality of wavelengths characteristic of different colors and wherein packs of fiber optics are utilized to carry selected color light for presentation at predetermined locations on the model object. The ends of the optic fibers of the model are received in the model at selected distances from a face thereof as desired to provide desired angles of view whereat the lights become apparent to the viewer of the multicolor holographic image dependent upon the use to which the resultant holographic image is directed. One such use is in the simulation of a Fresnel Lens Optical Landing System used aboard aircraft carriers.

Apparatus and method for the visual display of an object, such as an aircraft, at continuously variable attitudes comprising two hologram films of the object made in wrap-around 360.degree. fashion on axes through the object and normal to each other to store object images comprising a complete spherical view of the object and the provision of scanners, a laser beam source, reflectors and an instructor's control panel of amplifiers and switching circuits to direct the laser beam to the film having the view desired and at an xy address on the film at which the desired view is located and a display screen for viewing the selected image or series of continuously variable images.

A landing signal officer trainer having a cylindrically rolled holographic ilm with stored attitude data of yaw and pitch rotatably and slidably mounted in conjunction and relation to a laser beam source to vary yaw and pitch image attitude of a plane, a pechan prism rotatable to vary roll of the plane image, a zoom lens system to vary range of the plane image, enlarging lens apparatus to present an adequate image to a landing signal officer (LSO) observing the image, and a control panel operable by an instructor to vary the plane attitude and range position in accordance to the signals given by the trainee and thus provide unprogrammed training in guiding landing aircraft without use of actual equipment and in a manner in which the trainee participates. The invention further contemplates the provision of a ship holographic image variable in pitch and control apparatus for selectively coordinating plane range and ship pitch to produce land or abort conditions.

A package for a holographic storage media (10) is provided that utilizes a slide tray (43) for containing a plurality of slides (102). Each of the slides (102) is comprised of an opaque casing (110), which is operable to hold a sandwich structure (120). The sandwich structure (120) has a gripping mechanism (122) disposed on the edge thereof for allowing the structure (120) to be reciprocated within the jacket (110) for extraction thereof and reinsertion thereof. A gripping arm (156) is operable to attach to a gripping member (124) on a gripping mechanism (122) attached to the slide (102) to extract the slide (102) and place it into a holder (148). The holder (148) is then operable to receive the slide (102) and dispose it in a holographic storage system. The slide (102) can then be written to by interfering a data beam and a reference beam in a predetermined storage location (54) and then the slide again placed into the jacket (110).
