    摘要: An endoscopic apparatus for measuring blood flow contained within an enclosed body cavity is claimed. Such apparatus comprises an electromagnetic radiation source (6) for emitting a coherent beam, an optical relay system for propagating the beam down an endoscopic probe to illuminate a target (10) within an enclosed cavity, an endoscopic optical relay system for capturing the reflected light and transmitting an image of the illuminated region onto the surface of a two-dimensional image sensor (1), an analog to digital conversion device for capturing analog output signals from the image sensor for conversion to digital format, a display device for immediate visual display of captured images, a method for calculating flow values from a captured digital image containing speckle structure information of the laser illuminated surface, a memory device for storing digital blood flow images, and a display device for immediate visual display of color coded, blood flow images.
