Acousto-optic supermultispectral imaging
Applied Optics, 1993An assumption of supermultispectral imaging is presented. The focal point is to encode an object between spatial and spectral information with a tunable bandpass filter, which is called the spatial-spectral encoder. Theoretical and experimental results have verified that the assumption is correct.

Acousto-optic image processing
Applied Optics, 2008Acousto-optic processing of images is based on the angular selectivity of acousto-optic interaction resulting in spatial filtration of the image spectrum. We present recent theoretical and experimental investigations carried out in this field. Much attention is given to the analysis of the acousto-optic cell transfer function form depending on the ...

Optical image encryption topology
Optics Letters, 2009Optical image encryption topology is proposed based on the principle of random-phase encoding. Various encryption topological units, involving peer-to-peer, ring, star, and tree topologies, can be realized by an optical 6f system. These topological units can be interconnected to constitute an optical image encryption network.

Integrated optical imaging system
Applied Optics, 1990A planar version of a 4f imaging system is described where the input object and the lenses are integrated on one side of a single quartz glass substrate. The lenses were implemented as diffractive lenses with four discrete phase levels.

Coherent array optical imaging
Applied Optics, 1991This paper describes a technique that allows a severely distorted coherent optical array receiver to produce images comparable to conventional monolithic imaging systems. The technique is based on using a phase synchronizing point source as a reference to eliminate phase errors in the array.

Survey of Ophthalmology, 1989
Fundus imaging and photography are cornerstones of modern ophthalmic practice. The recent developments in electro-optic and computer imaging technology resulted in many improvements in the acquisition and analysis of fundus images, which already are being used in commercial fundus imaging systems.

Urologic Oncology: Seminars and Original Investigations, 2009
Optical imaging is useful during preclinical drug development for monitoring biomarkers and molecular events in living tissue. In animal models, the technology has been used to monitor tumor growth and metastasis, determine biological effects of novel drugs, monitor tumor enzyme activity, and examine host-tumor interactions.
