Generation device and method of parallel light path in vertical direction

Abstract

The invention discloses generation device and method of a parallel light path in the vertical direction. The device comprises a laser source, a total reflection mirror and an oil immersion lens, wherein the laser source is arranged corresponding to the total reflection mirror, and the total reflection mirror is correspondingly arranged below the total reflection mirror. The method comprises the following steps of: emitting horizontal incident laser by adopting the laser source and reflecting the laser through the reflection mirror to ensure that the laser is vertically irradiated on the surface of the oil immersion lens to return vertical reflection laser; and on a long light path, guaranteeing that the incident laser and the reflection laser completely coincide through lens paper. By utilizing the light path, a light path strictly vertical or parallel to the ground surface can be obtained, thus the device can be used for measuring the parallelism of a large-area experiment platform in a laboratory and guarantee the verticality of a high building to the ground surface in a field experiment.

Description

technical field [0001] The invention relates to a device and a method for generating parallel optical paths in a vertical direction, and belongs to a device and a method for measuring levelness and verticality by using an optical path. Background technique [0002] Prior art: The horizontal accuracy of the reflector on the horizontal surface is ensured by horizontally installing the reflector on the experimental platform, and the levelness of the experimental platform is generally calibrated by using a mercury level. [0003] Existing defects: Even if the large-area experimental platform can guarantee a certain level, the level of the small-area reflector fixed on the experimental platform can only be achieved by fine-tuning the mechanical device, and it is difficult to maintain a high level. The levelness of the surface of the reflector is guaranteed by fine-tuning the mechanical device, but the fine-tuning takes a certain amount of time. Contents of the invention [000...
