Abstract
Detector de grietas en superficies metálicas en movimiento, mediante un sistema optoelectrónico que comprende un emisor láser cuyo punto de láser o "spot" es regulable, y que emite en dirección oblicua a la superficie examinada, y un fotodetector que capta el haz reflejado en dirección oblicua, conectados a una tarjeta electrónica que permite activar un sistema de alarma cuando se detecte una grieta en la superficie examinada. 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.
