Abstract:
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.

Claim (Index 1):
A device for measuring the speed of blood in a blood vessel of the eye, comprising:\n a coherent light source for generating a source beam; two detectors provided with entrance apertures to receive two light beams backscattered by a blood vessel; an optical system comprising; a Dove prism crossed by the source beam and the backscattered beams and capable of being rotatably adjusted around an axis parallel to the source beam crossing it, and a focusing system capable of forming the image of a blood vessel on the entrance apertures;\n a signal processor capable of processing the signals from the detectors; and \n an optical element which can be inserted during the device adjustment phase to transform the light spot supplied by the light source into a line coplanar with the source beam and the backscattered beams selected by the apertures, \n the device being coupled with a fundus camera to aim into the fundus of the eye at a selected blood vessel and to align said line with the tangent to the blood vessel at the illumination point by means of a rotation of the Dove prism.
