Abstract

The invention discloses a high-precision optical path debugging device and a debugging method thereof, the high-precision optical path debugging device comprises a light source module and a receiving module, the light source module is used for providing reference light and receiving feedback signals in the debugging process, and the receiving module is used for testing the position and the directional angle of a light beam before and after optical path debugging; the light source module comprises an adjusting support, an optical fiber collimator, a reference light source and a first spectroscope. Light outputted by the reference light source is inputted into the optical module to be debugged through the optical fiber collimator and the first spectroscope. The receiving module comprises a partial reflection beam splitter, a second spectroscope, a coaxial focusing lens, a first light spot machine and a second light spot machine, light outputted by the optical module to be debugged passes through the second spectroscope and then is emitted to the first light spot machine and the coaxial focusing lens, and the light focused after passing through the coaxial focusing lens is inputted into the second light spot machine. According to the invention, the relation between the incident light in front of the optical module and the emergent light behind the optical module can be accurately controlled and monitored, a visual debugging scheme is provided, and the debugging efficiency is high.

Description

technical field [0001] The invention relates to the technical field of optical light paths, in particular to a high-precision optical light path debugging device and a debugging method thereof. Background technique [0002] Optical optical path debugging is the core process in the field of optical machine assembly and laser application. In many optical adjustment applications, such as laser cavity adjustment, fiber coupling, space communication adjustment, etc., such applications often require that the position of the output light of the module coincides with the position of the input light, and the angle between the two needs to meet <10” (0.05mrad), therefore, how to achieve high-precision optical path debugging is a problem that must be considered in the field of optical machine assembly. [0003] Because in the complex optical path system, the optical path reference light is often not visible light, in order to facilitate high-precision adjustment, some auxiliary vis...
