ABSTRACT:
A method and apparatus for the non-destructive identification of coated and uncoated metal parts employing infrared thermography. The apparatus comprises a means for directing infrared radiation onto the surface of a part; a means for scanning the part surface for reflected infrared radiation; a means for capturing the reflected radiation and converting it into a signal representative of variations in radiation reflected from the surface of the part; means for etching an identifying code into the surface of the part; and means for displaying the signal as a video image. The method comprises altering the surface reflective characteristics of a part to produce an identifying code, irradiating the part with infrared radiation of a specific wavelength and detecting differences in the amount and intensity of radiation reflected from the part.
