Abstract

A printed circuit generator utilizing the advantages of holography is realized by the following method. A laser beam is directed through an electro-optic shutter and brought to a point source S by a lens. Source S is utilized to develop two images R and 0 which, in combination with rotatable mirrors X and Y, develop a reference beam and an object beam. To make a hologram construction of a vertical line for example, mirror Y is stationary while mirror X is rotated continuously through an angle sufficient to trace the path of the desired line. During the beam scan, the electro-optic shutter is controlled to turn the laser beam on and off in a pulsating manner. The duration of each pulse is a function of the beam scan and the resolution limit defined by angle A.

Synthetic Holographic Printed Circuit Generator

A printed circuit generator utilizing the advantages of holography is realized by the following method. A laser beam is directed through an electro-optic shutter and brought to a point source S by a lens. Source S is utilized to develop two images R and 0 which, in combination with rotatable mirrors X and Y, develop a reference beam and an object beam. To make a hologram construction of a vertical line for example, mirror Y is stationary while mirror X is rotated continuously through an angle sufficient to trace the path of the desired line. During the beam scan, the electro-optic shutter is controlled to turn the laser beam on and off in a pulsating manner. The duration of each pulse is a function of the beam scan and the resolution limit defined by angle A. To produce a hologram of a horizontal line the roles of mirrors X and Y are reversed.
