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
The present invention relates to a kind of device and method of generation of vertical direction parallel light path, belong to the device and method that utilizes light path to measure levelness and verticality.
Background technology
Prior art: the guaranteeing of the horizontal accuracy of the catoptron of horizontal surface realized by the catoptron level is installed on the experiment porch, and the levelness of experiment porch is generally calibrated by using the mercury level to discuss.
The defective that exists: even large-area experiment porch can guarantee certain levelness, but the levelness that is fixed on the small size catoptron on the experiment porch can only be finely tuned by mechanical hook-up and be realized, be difficult to the high levelness of maintenance, promptly enable to finely tune the levelness that guarantees that mirror surface is certain by mechanical hook-up, but the fine setting needization regular hour.
Summary of the invention
The present invention seeks to carry, utilize the surface reflection of oily mirror, produce strict vertical parallel light path, utilize three beams vertical parallel light can find telescopical focus at the defective that prior art exists.
The present invention adopts following technical scheme for achieving the above object:
The generation device of vertical direction parallel light path of the present invention is characterized in that comprising LASER Light Source, completely reflecting mirror and oily mirror, the wherein corresponding setting of LASER Light Source with completely reflecting mirror, and oily mirror correspondence is arranged at the catoptron below.
Described completely reflecting mirror and oily mirror are at 45 mutually.
The production method of the light path of the generation device of vertical direction parallel light path is as follows:
The incident laser that adopts LASER Light Source emission level direction is by mirror reflects, and vertical irradiation returns vertical reflector laser to oily mirror surface; On long light path, scioptics paper guarantees that incident laser and reflector laser overlap fully.
The present invention utilizes this light path can obtain and the strict vertical or strict parallel light path in the face of land.In the laboratory, can be used for measuring the depth of parallelism of large tracts of land experiment porch.Experiment can be guaranteed the verticality on the high-lager building and the face of land in the open air.
