ABSTRACT:
The invention relates to a method for measuring the speed of a particle such as a red blood cell moving inside a flow such as a flow of the blood, using a light scanning microscope. The inventive method comprises the following steps: acquisition of an image by x and y light scanning on a plane containing the object; detection on the plane (x, y) of a mark on the plane (x, y); estimation of the speed vgof the object from the gradient thus determined.
