When laser light which has been scattered off a rough surface falls on another surface, it forms an "objective speckle pattern". 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 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. LSCI is a non-invasive technique to measure blood perfusion.

Offering a compact size, integrated drive electronics, and vibration-less speckle reduction, Optotune Laser Speckle Reducers are ideal for beam homogenization, 3D scanning, metrology, microscopy, and interferometry.

Laser Speckle Contrast Imaging. The first biomedical application was reported by Fercher and Biers.

Optimisation of a self-mixing laser displacement sensor The influence of speckle has also been reduced so that the sensor can now measure up to the

Laser Speckle Contrast Image. Neurovasculature in the mouse motor cortex imaged through a cranial window implant with a 685 nm laser.

The speckle pattern may be suppressed in certain lasers, such as those with a large optical bandwidth.
