Abstract (en)

[origin: WO2006114490A2] The inventive photothermal test camera (16) is provided with a laser beam (4) shaping system (22) comprising a device (40) for extending the laser beam section in such a way that a heating area (2) extended in a direction (D) is formed on the surface of a testable piece (1), an array (8) of infrared sensors (10) for detecting a infrared radiation transmitted by a detection area (3) on the surface (1a) of the piece (1) with respect to the heating area (2) and a unit (46) for processing signals transmitted by the infrared sensors (10) in such a way that a thermographic image of the piece (1) surface (1a) is produced by scanning said surface (1a) with the aid of the heating area (2). An extending device (40) is embodied in the form of an optical device. Said invention can be used for non-distructive testing.
