Problems solved by technology

The optical system of the Herriott type long-range pool is composed of two concave reflectors. It is characterized by a simple structure and relatively easy adjustment of the optical path, but the aperture angle is small. It is suitable for laser light sources, but the number of optical paths of these multiple optical paths is fixed. , there is no multi-path device with variable optical path number

Embodiment Construction

[0040] The present invention proposes a multi-optical path method and device for realizing multi-optical paths and changing the number of optical paths, comprising the following steps:

[0041] 1) After the light incident on the corner mirror 1 is emitted from the corner mirror 1, it is reflected back to the corner mirror 1 by the first reflector 3; the specific implementation method is: the light incident on the corner mirror 1 is reflected three times inside the corner mirror 1 The outgoing light is reflected by the first reflector 3 and returns to the corner mirror 1. The first reflector 3 here can be a right-angle reflector; the placement position requires that the light can be reflected by it and then return in the original direction. 1, and the plane is parallel to the incident ray. The light incident on the corner mirror 1 is reflected three times inside it and then emerges. The outgoing light and the incident light are parallel to each other and symmetrical with respe...

Abstract

The present invention proposes a multi-optical path method and device for realizing multi-optical paths and changing the number of optical paths. The method includes the following steps: 1) after the light incident on the corner mirror exits from the corner mirror, it is reflected back by the first reflector. Corner mirror; 2) Step 1) The light returning to the corner mirror is reflected by the second reflector after being emitted by the corner mirror; wherein, the second reflector rotates clockwise or counterclockwise around the axis of symmetry of the corner mirror to form a changing number of optical paths; 3) in step 2), the light returned to the corner mirror is all emitted after being reflected by the corner mirror; the present invention proposes a method and method for realizing multiple optical paths and changing optical paths that are relatively low in calibration accuracy and are easy to engineering realization A device that can be used as a moving device or a fixed device to realize multiple optical paths and change optical paths.

Description

technical field [0001] The invention belongs to the field of optical technology, and relates to a multi-optical path method and device for realizing fixed and variable optical paths by using a corner mirror. Background technique [0002] Spectroscopy is an important means to obtain material structure and chemical composition, determine the content of material elements, and study atomic energy levels. It has been widely used in industrial and agricultural production, scientific research, environmental monitoring, aerospace remote sensing and other fields. [0003] The emergence of interferometric spectrometers overcomes the shortcomings of low energy utilization of traditional dispersive spectrometers (splitter prisms, dispersive prisms, and diffraction gratings, etc.), while time-modulated interferometric spectrometers inherit the advantages of traditional interferometric spectrometers and integrate multiple channels (Felleget advantages) , high throughput (Jacquinot advanta...
