Abstract
Abstract A method of generating a holographically reconstructed image of a model object 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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
169 words
The method of generating a holographically reconstructed image of a model object so that said image will appear to have lamps of various predetermined color at predetermined locations and said method comprising the following steps: a. providing a model object, b. providing a laser light source having a laser beam output comprising a plurality of wavelengths characteristic of different colors, c. providing a light source divider means positioned to divide a portion of said beam into characteristically colored beams, d. providing a plurality of light transmitting fibers, each having one end positioned to receive light from a selected one of said colored beams and the other end located at said model in one of said predetermined locations so as to emit light of said selected color, e. applying said laser beam to generate a hologram of said model and said light emitting fiber ends, and f. illuminating said hologram with said laser beam to generate said holographically reconstructed image including the light pattern of said light emitting fiber ends.
Claim 2
Independent Claim
169 words
The method of generating a holographically reconstructed image of a model object so that said image will appear to have lamps of various predetermined color at predetermined locations and said method comprising the following steps: a. providing a model object, b. providing a laser light source having a laser beam output comprising a plurality of wavelengths characteristic of different colors, c. providing a light source divider means positioned to divide a portion of said beam into characteristically colored beams, d. providing a plurality of light transmitting fibers, each having one end positioned to receive light from a selected one of said colored beams and the other end located at said model in one of said predetermined locations so as to emit light of said selected color, e. applying said laser beam to generate a hologram of said model and said light emitting fiber ends, and f. illuminating said hologram with said laser beam to generate said holographically reconstructed image including the light pattern of said light emitting fiber ends.
Claim 3
Dependent Claim
38 words
The method according to claim 1, including a. the step of grouping said light transmitting fibers in fiber optic bundles to provide for multiple lights of the same color at the object end in selected locations as desired.
Claim 4
Dependent Claim
28 words
The method according to claim 1, including a. the step of recessing said optic fiber ends in said model object a distance determining desired predetermined sectors of viewability.
Claim 5
Dependent Claim
121 words
The method according to claim 2, including a. forming said model object of the model of an aircraft carrier and a holder mounted thereon for receiving the object ends of said fibers, b. forming a first plurality of horizontal spaced passageways central and above said base line in said holder, each succeeding passageway above the base line being inclined upwardly at successively increasing angle to receive fibers carrying yellow color light, and d. forming a downwardly inclined passageway in said holder to receive a fiber carrying red light, whereby said green, yellow and red light carrying fibers present a Fresnel Lens Optical Landing System pattern and provide predetermined sectors of viewability to a trainee pilot in a holographic carrier landing trainer.
Claim 6
Dependent Claim
42 words
The method according to claim 4, including a. varying the position of said optic fibers longitudinally in said passageways to vary the degree of viewing angle to a desired viewing angle suitable to the approach landing pattern desired in the ultimate hologram.
