A design method for a double-grating Bragg diffraction structure with a Rowland circle structure

Abstract

A design method for a Bragg diffraction double grating structure of a Rowland circle structure, comprising a housing, a connecting groove in the housing, a plurality of grating columns fixed in the connecting groove, the grating columns arranged in sequence along the connecting groove, light-transmitting slits between the grating columns, and the light-transmitting slits spaced on both sides of the grating columns. Light passes through the grating columns, and then enters the light-transmitting slits next to the grating columns. The light passes through the scattered edges on the grating columns, causing the light to be diffracted. The scattered edges on the grating columns can make the diffraction of the grating columns more convenient and efficient, can meet the convenience of use in different working conditions, can make the diffraction work effect better, can work stably in different environments, and the grating columns are arranged in the connecting grooves, so that the connecting grooves can fix the grating columns more conveniently and firmly.

Description

Technical Field

[0001] The invention relates to a grating, and in particular to a design method for a Bragg diffraction double grating structure of a Rowland circle structure. Background Art

[0002] Gratings are needed in many fields that require light refraction. Gratings can refract light. In places where gratings are used, the refraction of light can be better and more stable. Many gratings are not very convenient to use when light refraction is needed, especially in places where the light is not very bright, which affects the further use of the gratings. The working effects of some gratings are affected, which affects the use and stability of the gratings in the workplace, resulting in the gratings not being diffracted well outside the grating when diffracting. Summary of the invention

[0003] The purpose of the present invention is to provide a method for designing a Bragg diffraction double grating structure of a Rowland circle structure with simple structure and high diffraction efficiency.

[0005] The grating column is a cylindrical structure and is fixed in the connecting groove.

[0006] The connection groove and the shell are connected to each other to form an integral structure, and the shell is arranged on the top of the connection groove.

[0007] The shell is divided into an upper shell and a lower shell. A connecting groove is arranged on the upper shell, and a grating column is arranged in the connecting groove.

[0008] A transition plate is arranged on the lower shell.

[0009] The transition plate is connected to the lower end shell, and the upper end of the transition plate is connected to the grating column.

[0010] The grating columns are provided with scattered edges.

[0011] The dispersed edges are arranged on both sides of the grating column.

[0012] The advantages of the present invention are: the grating columns are provided with dispersed edges, which can make the diffraction of the grating columns more convenient and efficient, can meet the convenience of use in different working conditions, can make the diffraction work effect better, can work stably in different environments, and the grating columns are arranged in the connecting grooves, so that the connecting grooves can fix the grating columns more conveniently and firmly.
