Speckle imaging describes a range of high-resolution astronomical imaging techniques based on the analysis of large numbers of short exposures that freeze the variation of atmospheric turbulence. They can be divided into the shift-and-add method and the speckle interferometry methods. These techniques can dramatically increase the resolution of ground-based telescopes, but are limited to bright targets. Combined laser speckle imaging and fluorescent intravital microscopy for monitoring acute vascular permeability reaction. Optical clearing agents (OCAs) and many chemicals are widely used in functional diagnosis of skin tissues. Numerous studies are associated with the transcutaneous diffusion of OCA in epidermal, dermal, and hypodermal tissues, which results in changing their optical properties. Laser Speckle Imaging (LSI) is a non-invasive blood flow imaging technique that can provide information on the state of biological tissues and the efficiency of disease treatment.

Results and Presented by Lung W. Lau at the "i3: Shark Tank" session during the SAGES 2019 Annual Meeting in Baltimore, MD on Thursday, April 4, 2019 Laser Speckle in Medical Imaging - LaserLabMed Laser speckle is an interference phenomenon that is observed when coherent light (e.g.laser) is scattered from a diffusing surface. In general, a speckle pattern is a random pattern whose properties can be described using stochastics and probabilistic laws.

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.

2012-04-29 · and makes random lasers uniquely suited for imaging applications. To demonstrate that a low-spatial-coherence random laser does in fact enable speckle-free imaging, we compared images generated with random laser illumination to those generated by other common light sources: a narrowband laser, a broadband laser and an LED. Laser Speckle Imaging permitted immediate real-time visualization and measurement of relative cortical perfusion in excellent image quality and high spatial-temporal resolution in all patients. Positive and negative prediction limits of infracted tissue were determined at 40% and 110% of baseline perfusion, respectively.
