Phase correction in holographically produced gratings
(Elsevier, 1974-10)
Several technques for producing holographic optical elements that are free from the inherent phase errors of their substrate irregularities are given.
Long range, high resolution laser radar
(Elsevier, 1994-01-15)
A high energy, chirped pulse laser was used to demonstrate long range, high resolution radar. A broadband nanosecond chirped pulse propagated to a target, and upon compression sub-millimeter surface resolution was obtained. ...
