Abstract

The opto-electronic device for supervision or examination of the surface of an object (1) comprises an optic head (3) with a bundle (7) of microguides achieved in a substrate (5), and terminating on a photodetector line array (15). The line array is connected to an electronic device (19,22,23,24) for processing and display of the light information transmitted by the optic head (3) and representative of the surface state of the object (1).
