摘要:
The invention relates to a device for measuring the speed of blood in a blood vessel of the eye. Said device includes: a light source (5), two detectors provided with input diaphragms (36, 46) for receiving two light beams backscattered by a blood vessel, an optical system including a Dove prism (70) through which the source beam and backscattered beams pass and which is rotatably adjustable about an axis parallel to the source beam passing therethrough, and a focusing system (62) capable of forming the image of a blood vessel on the input diaphragms, a processor capable of processing the signals from the detectors, and an opitcal element (52) that can be inserted during the device adjustment phase so as to convert the light spot, provided by the light source, into a line coplanar with the source beam and the backscattered beams.
