INVISIBLE LASER SYSTEM AND LIGHT PATH VISUALIZATION METHOD THEREFOR

摘要

An invisible laser system (200) and a light path visualization method therefor, which fall within the technical field of lasers. The invisible laser system (200) comprises: an invisible laser generator (210) for generating an invisible laser (211); a visible light generator (240) for generating visible light (241); and light path visualization components (250, 300, 400, 500) which are arranged in light paths of the invisible laser (211) and the visible light (241) and at least comprise a first incident end, a second incident end and a first emitting end, wherein the invisible laser (211) is incident at the first incident end, the visible light (241) is incident at the second incident end, and all the invisible lasers (211) and at least a part of the visible light (241) are emitted in parallel at the first emitting end. Thus, all the invisible lasers (211) merely exist in a direction parallel to a light path of the visible light (241), while the other directions do not have the invisible lasers (211), thereby eliminating radiation risk.
