Optical scanning system for surface of object being tested - has circular receiving reflector formed by at least two separated segments leaving gaps so that rotational symmetrical object for testing can be gripped for imaging

摘要

The reflector (2) has a conical or shell shaped mirror surface and a centrally arranged passage opening. The reflector deflects reciprocally the light emanating from the light source onto the test object (5) around a circumferential strip. The imaging light beam (7) is focussed on a sensor (11), using at least one imaging lens (10). An electrical evaluation unit is connected to the sensor. The circumferential reflector (2) consists of at least two separate parts (2', 2''). The parts form segments arranged opposite each other with mutual spacing. Two gaps (4'. 4'') are arranged between them so that the movable object under test enters in the space enclosed by the reflector, laterally without axial relative movement w.r.t. the reflector. USE/ADVANTAGE - Bottles, lamps and other rotationally symmetrical objects. Allows no reciprocating movement along main axis of system but permits continuous lateral movement.
