Laser Speckle Contrast Imaging (LSCI)

LSCI is a non-invasive technique to measure blood perfusion. The method that visualizes tissue blood perfusion in real time. 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 light from the area illuminated by the laser. Blood perfusion is calculated by analyzing the variation in the speckle pattern. The speckle pattern is recorded in real time at a rate of up to 100 images per second, with a resolution of 100 μm/pixel.
