Abstract

The invention provides a preparation method of a waveguide module. Comprising the following steps: S1, obtaining a first waveguide sheet, and carrying out dispensing treatment on the edge part of the surface of one side of the first waveguide sheet; s2, acquiring a second waveguide sheet, and placing the second waveguide sheet on the corresponding laminating platform, so that the second waveguide sheet is located on one side, with the glue, of the first waveguide sheet; s3, a laser interference altimeter is adopted to adjust the distance between the first waveguide plate and the second waveguide plate, a height measurement module of the laser interference altimeter is started, and a fitting platform of the first waveguide plate is adjusted to move in the direction close to the second waveguide plate; when the height measurement module detects that the distance between the first waveguide sheet and the second waveguide sheet is a preset distance, the attaching platform of the first waveguide sheet stops moving; and S4, carrying out curing treatment on the first waveguide sheet and the second waveguide sheet by adopting ultraviolet rays to form the waveguide module. The invention solves the problem that the alignment precision and the glue thickness are difficult to guarantee in the preparation of the waveguide module in the prior art.

Description

technical field [0001] The invention relates to the technical field of optoelectronics, and in particular, to a preparation method of a waveguide module. Background technique [0002] Augmented Reality AR (Augmented Reality) technology is a technology that skillfully integrates virtual information with the real world. These kinds of information complement each other, thereby realizing the "augmentation" of the real world. AR glasses are one of the products with the most potential applications of AR technology. Most of its optical technology is reflected, refracted, and diffracted through optical waveguide modules, and finally imaged on the user's retina. There are various types of waveguide modules. Taking AR optical waveguide glasses as an example, AR optical waveguide glasses currently require the superposition of RGB three colors and the superposition of the protective cover. The diffraction optical waveguide has a low utilization rate of light, and the coupling area Th...
