Laser speckle contrast imaging (LSCI) is an imaging tool in which speckle patterns in dynamic systems are analyzed to detect flow.

Laser speckle contrast imaging (LSCI) is an imaging tool in which speckle patterns in dynamic systems are analyzed to detect flow. LSCI takes advantage of the fact that during long exposure time imaging of dynamic systems, the particle movement results in temporal variations that blur the speckle pattern, resulting in decreased contrast (also referred to as fringe visibility).

Laser Speckle Contrast Imaging (LSCI) is a wide field of view, non scanning optical technique for observing blood flow. Speckles are produced when coherent light scattered back from biological tissue is diffracted through the limiting aperture of focusing optics. Mobile scatterers cause the speckle pattern to blur; a model can be constructed by inversely relating the degree of blur, termed Laser speckle contrast imaging (LSCI) is a technique based on the dynamic change in this backscattered light as a result of interaction with red blood cells. It can be used to visualize perfusion in various tissues and, even though this technique has been extensively described in the literature, the actual clinical implementation lags behind. The first part of this paper is a review of the technique known variously as laser speckle contrast imaging (LSCI), laser speckle imaging (LSI), or laser speckle contrast analysis (LASCA). The technique uses the phenomenon of laser speckle.

The system uses an invisible 785 nm laser beam that is spread over the surface of the skin by a diffuser, creating a speckle pattern formed by random interference in the backscattered Laser Speckle Contrast Imaging Overview LSCI is a simple technique that requires only a camera with an appropriate lens, a low-power monochromatic (i.e. single-colour) laser, and a lens to expand the laser beam. Laser speckle contrast analysis (LASCA), also known as laser speckle contrast imaging (LSCI), is a method that instantly visualizes microcirculatory tissue blood perfusion. It is an imaging technique that combines high resolution and high speed. Laser Speckle Contrast Imaging (LSCI) is a wide field of view, non scanning optical technique for observing blood flow.

However, the limitations of light penetration imaging techniques hinder the detection of blood flow in deep brain tissues in vivo. Hence, in this Letter, we present a gradient index lens-based laser speckle contrast imaging system for time-lapse blood flow detection in subcortical regions of the brain.

The imaging technique has a high Laser Doppler imaging has a linear response to speed changes over the whole range of detectable velocities.

2011-03-01 · Laser speckle contrast imagers allow real time (up to 200 Hz) CBF measurements on large surface areas without contact to the skin. The principle for the measurement of CBF by speckle lasers differs somewhat from that of the laser Doppler flowmetry.

One example that uses this encoding allows the measurement of flow or time dependent variations in the surface.
