Linear effect laser switching device

Abstract

According to the linear effect laser switching device provided by the invention, switching of linear optical effects of various fan angles can be realized by rotating a single optical element, the operation is simple, engineering requirements are utilized, and the equipment cost is reduced. The device comprises a laser, a first reflecting mirror, a second reflecting mirror, N Powell prisms and a rotating shaft structure, an emergent light beam of the laser device is parallel light, and the emergent light beam of the laser device is arranged towards the first reflecting mirror; a second reflector is arranged behind the output of the first reflected light beam of the first reflector, and N Powell prisms are annularly distributed on the annular surface where the output position of the second reflected light beam of the second reflector is located; one side of the non-reflecting mirror surface of the second reflecting mirror is connected with an output shaft of the rotating shaft structure; a second reflection light beam of the second reflector corresponds to N emergent positions, and a corresponding Powell prism is arranged behind the output of each corresponding emergent position.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a line effect laser switching device. Background technique [0002] The existing one-line laser irradiates the incident curved surface of the Powell prism with a single beam of laser light, and then emits a uniform straight beam through the exit surface of the Powell prism. The existing one-line laser products can only generate one-line beams with a specific fan angle. Line optical effect, when other fan angles need to be used, it is necessary to re-purchase a word-line laser, which makes the purchase cost high, and when the operation base point is the same position, it is necessary to reset the position of the equipment, which makes the adjustment time-consuming and cannot ensure fast use. . SUMMARY OF THE INVENTION [0003] In view of the above problems, the present invention provides an in-line effect laser switching device, which can realize the switching of in-line optical...

Problems solved by technology

[0002] The existing inline laser emits a uniform straight beam through the incident surface of the Powell prism through a single beam of laser light. The existing inline laser products can only produce inline beams with a specific fan angle. Line optical effect, when other fan angles need to be used, a word line laser needs to be repurchased, which makes the purchase cost high, and when the operating base point is at the same position, the position of the device needs to be reset, which makes adjustment time-consuming and cannot ensure fast use
