Optoelectric crack detector in moving metal surfaces

Optoelectric crack detector in moving metal surfaces.Optoelectric crack detector in moving metal surfaces using an optoelectric system that includes a laser transmitter whose laser point or "spot" is adjustable, and that transmits in a direction that is oblique to the examined surface, and a photodetector that can capture the beam reflected in an oblique direction, connected to an electronic card that allows activating an alarm system when a crack is detected on the examined surface. The detection is based on the drop in reflected optical power that is captured by the photoreceiver, and therefore does not require any subsequent processing through CCD or analogue systems, of the detected signal. It is useful for the detection of cracks on moving mounting chain links.

La detección se basa en la caída de la potencia óptica reflejada que es captada por el fotorreceptor, y por tanto no precisa ningún tratamiento ulterior, por CCD ni sistemas análogos, de la señal detectada. Es útil para la detección de grietas en eslabones de cadenas de montaje en movimiento.
