3614234 FRINGE-GENERATING HOLOGRAPHIC SYSTEM  
A double-exposure holographic system having means for producing finite fringes at the plane of an object. To this end a first hologram is made without the object and by passing the scene beam...
3603662 TWO-BEAM, WIDE-VIEWING ANGLE HOLOGRAPHIC APPARATUS  
Holographic apparatus for taking holograms in transmission with lasers of limited coherence permitting a wide-viewing angle on the order 50° to 60°. The apparatus features an angle between the...
3602570 APPARATUS FOR MAKING ANNULAR HOLOGRAMS  
An "annular" hologram is produced by the interference between at least a portion of a reference beam of coherent light confined to a circular annular region symmetrically disposed about a given...
3598467 FIBER OPTIC DIFFUSER FOR HOLOGRAPHY  
a4 182 A holographic apparatus capable of utilizing a pulsed laser developing an incompletely coherent light beam for recording holograms. The apparatus makes use of a bundle of transparent fibers...
3580655 WAVEFRONT RECONSTRUCTION  
This invention is directed to methods and apparatus for capturing various patterns of electromagnetic energy emanating from or as they are transformed after passing through an object and...
3578837 DOUBLE-DIFFUSER HOLOGRAPHIC SYSTEM  
A holographic system for recording holograms of an object in transmission. In order to make more uniform the spatial coherence and the intensity of the light beam of a laser, a light diffuser is...
