Abstract

The invention belongs to the field of optical application, and discloses a high-efficiency and high-brightness light path transmission method, which can greatly reduce the energy loss of a target light beam in a transmission process so as to remarkably improve the utilization rate of initial incident light energy and the illumination brightness. The first transmission P polarized light and the first reflection S polarized light are formed by polarizing and splitting preset incident light; then, the P polarized light of the first transmission light is converted into second transmission S polarized light, the second transmission S polarized light is reflected to obtain second reflection light, in light path conduction of light obtained from the preset incident light, all the light is converted into the first reflection S polarized light and the second reflection S polarized light, and light energy loss caused by the P light in the conduction process is greatly reduced. The invention further discloses an optical mechanism of the high-efficiency and high-brightness light path for implementing the high-efficiency and high-brightness light path transmission method. The optical mechanism comprises a polarization conversion prism group, a preset PBS film, a half-wave plate, a preset polaroid and a preset PBS prism.

Description

technical field [0001] The invention belongs to the field of optical applications, and in particular relates to an efficient and bright optical path transmission method and an optical mechanism. Background technique [0002] LcoS display technology is a display technology based on silicon-based CMOS integrated circuit technology, which uses reflection of external light to achieve imaging. Compared with other display technologies, it has high resolution, requires fewer peripheral ICs, and module packaging Due to its low cost and high utilization of light, it is widely used in many related fields, and AR display is one of the important directions in these fields. [0003] At present, the optical components in the LcoS package of AR are light source and prism / reflector, and the optical path formed by the combination is used to form the target beam required for imaging. [0004] However, in actual experience, the transmission of the target beam in the combined optical path stil...
