Laser Speckle Imaging System

Serial number


SIM BFI-HR Laser Speckle Imaging Systemis designed based on the new LSCI (Laser Speckle Contrast Imaging / LSCI) technology, with unique non-contact, high temporal and spatial resolution and technical advantages of full-field fast imaging,which provides a real-time dynamic blood flow monitoring and video imaging recording method for basic research in life sciences and clinical medicine. It is a vital basis for understanding tissue, organ pathology or physiological indicators. The instrument does not require any contrast agent, the time resolution can reach the order of milliseconds and the spatial resolution can reach the order of micrometers, which realizes the real-time observation of blood flow distribution status of microvascular and functional requirements for relative changes in blood flow values.
