摘要
The present invention relates to a system and method of acquisition of a digital manuscript writing, said system comprising - an optical sensor (1) including: - a surface element (4) - an imager (3), - a stylus (2) including: - a nozzle (21) is adapted to be brought into contact with the external face of the surface (7) of the surface element (4), in which the optical sensor (1) is an optical sensor biometric to total reflection, the angle of imager θcam is greater than the critical angle of the interface between the surface element (4) and the air, and in that the nozzle is at least partially covered with an outer surface layer made of a coupling having a refractive index n2, with n2 n3.sin (θcam), where n3 is the refractive index of the material constituting the surface element (4).
