Abstract (en)
[origin: FR2909182A1] The method involves forming two set of images of a scene in which an object e.g. eye, is found, through respective filters (F1, F2) whose bandwidths are adjusted on wavelengths (lamdba1, lambda2) during illumination of the object by laser pulses at the image sets, respectively, where one of the sets is in synchronism with the other set. A third set of image is formed by an image processing and controlling electronic block (CT), where the third set of image is the difference between the two sets of images. An independent claim is also included for an object detecting system comprising a laser emitter.
