Abstract
Research was continued on improvement of long-range image recognition, i.e., optical discrimination, and on certain laser pnenomena. It was desired to improve the image recovery of an object of finite size from its diffraction-limited image in order to enhance the remote observation of high- altitude objects, such as satellites, perceived through the fluctuating atmosphere. A new algorithm is proposed for computing the transfer of a band- limited function. In the laser area, the major task was the screening of atomic vapors, particularly metal vapors, for new, efficient lasers in the visible and ultraviolet spectral ranges, using computer-modeling and experimental methods. Several promising candidates are identified. In another vein, the theory of unstable resonator cavities was studied in relation to lasers, with a view toward improving the analytic methodology as a complement to numerical techniques and toward improving design by improving the understanding of the resonance phenomena in cavity configurations. A minor effort in this program period was devoted to completion of the final reportage on the experimental simulation of stratified ocean wakes in our thermally-stratified air wind- tunnel. The actual work had been completed in the prior program period.
