If a photographic plate or another 2-D optical sensor is located within the scattered light field without a lens, a speckle pattern is obtained whose characteristics depend on the geometry of the system and the wavelength of the laser. Laser speckle contrast imaging (LSCI) which can also be called laser speckle imaging (LSI) is an imaging modality based on the analysis of the blurring effect of the speckle pattern. The operation of LSCI is having a wide-field illumination of a rough surface through a coherent light source. Speckle patterns can severely degrade the image quality of laser projection displays, or disturb position measurements with laser pointers.

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.

2 The technique proposed by Fercher and Briers was non-real-time and had practical limitations due to the use of nondigital systems, which impeded the clinical use. The moorFLPI-2 blood flow imager uses the laser speckle contrast technique to deliver real-time, high-resolution blood flow images, providing outstanding performance in a wide range of pre-clinical and clinical research applications.

The method relies on the insertion of an intracavity phase diffuser into a degenerate cavity laser to break the frequency degeneracy of Laser speckle contrast imaging of collateral blood flow during acute ischemic stroke.

2021-04-22 · Laser speckle contrast imaging. This project is based on the observation by Lisa Richards et al at the University of Texas who noted that a medical imaging technique called laser speckle contrast imaging could be done with inexpensive and commonplace hardware: specifically a laser pointer and a webcam.
