WebKnife Edge Scanning. In this method, the beam is aimed at a sensor behind a spinning drum with several open sections that allow the laser to pass through. Each opening has a precise knife edge that “cuts” through the laser. Sensors detect exactly what portion of the beam reaches past the knife edge each time to determine shape, width and ... WebApr 11, 2024 · The quality of laser directly affects the laser sensors. The study of laser beam quality has always been an active field of laser science [8,9]. At the same time, the detection of laser beam quality is inseparable from the laser spot, so the detection and analysis of the laser spot has become an important research topic [10,11]. In laser ...
