Applied Optics, 1997
The temporal profiles of the parallel and perpendicular polarization components of a light pulse backscattered from a scattering medium are different. The depth of penetration into the tissue and depolarization of the backscattered light depend on the scattering and absorption characteristics of the tissue.

Optical imaging is experiencing significant technologic advances. Simultaneously, an array of specific optical imaging agents has brought new capabilities to biomedical research and is edging toward clinical use. We review progress in the translation of macroscopic optical imaging-including fluorescence-guided surgery and endoscopy, intravascular ...

Optical and Optoacoustic Imaging
2020The present chapter summarizes progress with optical methods that go beyond human vision. The focus is on two particular technologies: fluorescence molecular imaging and optoacoustic (photoacoustic) imaging. The rationale for the selection of these two methods is that in contrast to optical microscopy techniques, both fluorescence and optoacoustic ...

Fundamentals of Optical Imaging
2021Optical imaging, which possesses noninvasive and high-resolution features for biomedical imaging, has been used to study various biological samples, from in vitro cells, ex vivo tissue, to in vivo imaging of living organism. Furthermore, optical imaging also covers a very wide scope of spatial scale, from submicron sized organelles to macro-scale live ...

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 ...

Abstract This chapter considers the ability of a lens to produce an image, in particular the effect of the finite size of the lens and the Fourier relationship between the field in the lens plane and the field in the focal plane.

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.
