Fresnel lens film and system

Abstract

The invention relates to the technical field of Fresnel lens films, and discloses a Fresnel lens film and a system, wherein the Fresnel lens film comprises flexible silica gel; the flexible silica gel is processed through material preparation, stirring, heating, banburying and compression molding to obtain a semi-finished product of flexible silica gel, the prepared materials are placed in a stirring kettle according to different proportions to be uniformly stirred, a proper amount of water is added, and the silica gel material and a curing agent are fully and uniformly stirred for 1-2 hours to obtain a mixed liquid. Different films are pasted according to different calculation results through a covering film, and the 3D experience effect is enhanced for a semi-finished product according to different novel arrangement compositions; the film is prepared from the flexible silica gel, molecular arrangement of the film is changed in a certain process, and the effect of enhancing reality (3D) materialization is achieved. The designed software and hardware are operated, the Fresnel lens film after film pasting is tested, a user can start the 3D effect when needed, and the controllability of the 3D effect is achieved.

Description

technical field [0001] The invention relates to the technical field of Fresnel lens film, in particular to a Fresnel lens film and a system. Background technique [0002] Fresnel lens, also known as threaded lens, is mostly a thin sheet made of polyolefin material, and it is also made of glass. One side of the lens surface is smooth, and the other side is engraved with concentric circles from small to large. Its texture It is designed based on the interference of light and the requirements of relative sensitivity and receiving angle, and the requirements of the lens are very high. [0003] The Fresnel lens uses the special optical principle of the lens to produce an alternating "blind area" and "high-sensitivity area" in front of the detector to improve its detection and reception sensitivity. When someone walks in front of the lens, the infrared rays emitted by the human body will alternately enter the "high-sensitivity area" from the "blind area" continuously, so that the...

Problems solved by technology

[0004] After the production of different Fresnel lens semi-finished products, the molecular arrangement inside the semi-finished products is uncontrollable, and it is impossible to apply film to the Fresnel lens semi-finished products according to different calculation results, which may easily lead to the effect of the product not being obvious enough, and defects appear, which will make the customer's sense of experience reduce
