摘要: Endoscopes are well known devices used for examining surfaces contained within an enclosed cavity. Typical applications these the examination of tissues human body cavities or mechanical components engine compartments. An endoscopic apparatus measuring blood flow cavity is claimed. Such comprises electromagnetic radiation source emitting a coherent beam, optical relay system propagating beam down probe to illuminate target cavity, capturing reflected light and transmitting image illuminated region onto surface two-dimensional sensor, analog digital conversion device output signals from sensor format, display immediate visual captured images, method calculating values containing speckle structure information laser surface, memory storing color coded, images.
