Optical Processing Techniques for Simultaneous Pulse Compression and Beam Sharpening by Leith, Emmett N.

“…A technique is described in which the separate techniques of beam sharpening (by synthetic antenna methods) and pulse compression are converted into a single…”

Photography by Laser: The highly coherent light produced by the laser is used in a novel photographic process, in which the light-sensitive film, instead of recording an image, in effect records the light waves themselves by Emmett N. Leith, Juris Upatnieks
