| titleOfInvention | Laser scanner flaw detection system using baseline follower signal processing |
| abstract | A B S T R A C T The output of the detector of a laser scanner flaw detection system is processed to treat changes therein which are not related to the detection of flaws. Detector output is applied to a baseline extractor providing a moving average baseline signal which is fed with the detector output in one mode to a differential circuit producing a difference signal which is applied to a discriminator. In an alternative mode, the detector output is applied directly to the discriminator. The baseline extractor is coupled to a thres-hold circuit which is coupled to the discriminator. Signals from the dif-ferential circuit or from the detector are passed by the discriminator if they exceed a predetermined threshold to provide a flaw output. A clamp cir-cuit is also provided for removing ambient light on the detector from the detector output signal. |
