Imaging through a Confocal Optical Interference Filter
Semi-annual technical rept. summary 1 Dec 1971-31 May 1972
CATHOLIC UNIV OF AMERICA WASHINGTON DC INST OF OCEAN SCIENCE AND ENGINEERING
Pagination or Media Count:
The problem of spatial and temporal filtering of an image by a spherical mirror type of optical interference filter is formulated. Improvements over current optical filter designs by 1,000 in the temporal resolution of optical images appear feasible. Applications--including velocity, temperature and turbulence distribution measurements and acousto-optic image conversion--are discussed.
