Detection method, device and assembly for providing information to an optoelectronic detector and applications, in particular to cutting a skin

摘要

The invention relates to the provision of information to an optoelectronic detector, this information relating to an area of a surface situated in the field of detection of the detector. Latent light sources are distributed at points suitable for defining geometrical figures with a common centre, the sources are placed on the surface so that the common centre is situated substantially on the area and the sources defining one of the said figures which is considered as representing the information are turned on. The figure shows a detection assembly comprising a light-source emitter 3 in the field of detection of a video camera 1 connected to a computer 4.
