Tandem-pulsed acousto-optics: an analytical framework of modulated high-contrast speckle patterns
Physics in Medicine and Biology, 2015 Recently we presented acousto-optic (AO) probing of scattering media using addition or subtraction of speckle patterns due to tandem nanosecond pulses. Here we present a theoretical framework for ideal (polarized, noise-free) speckle patterns with unity ...

Image sharpening metrics and search strategies for indirect adaptive optics [PDF]
, 2000 Adaptive optics is concerned with the correction of turbulence induced aberrations and mis-alignments in optical systems. It is an expensive and complicated technology which has been developed for astronomy and defence applications.

Interferometric wavefront sensing for extreme adaptive optics [PDF]
, 2004 Adaptive optics is concerned with the correction of phase distortions in wavefronts which degrade the quality of images produced by optical systems. It was originally developed for both astronomy and the military, where the Earth's atmosphere causes ...

Dual Illumination Planar Doppler Velocimetry using a Single Camera [PDF]
, 2003 A Planar Doppler Velocimetry (PDV) illumination system has been designed which is able to generate two beams, separated in frequency by about 600 MHz. This allows a common-path imaging head to be constructed, using a single imaging camera instead of ...
