摘要: A non-contact, laser detection system for detecting the extended state of an object in continuous motion such as a drill bit. In bit embodiment, detected states are clean, clogged and broken. (200), first signal, indicative energy reflected from surface bit, is digitized compared to threshold. second amplified The digital signals analyzed by computer (202) detect
