Optical path folding system based on polarization beam splitter plate and wave zone plates

Abstract

The invention discloses an optical path folding system based on a polarization beam splitter plate and wave zone plates, which is composed of a polarizer, a first prism, a first wave zone plate, a reflector, the polarization beam splitter plate, a second prism, a second wave zone plate, a collimator objective and a third prism. The collimator objective is adhered with the second wave zone plate and then adhered with the second prism, the polarization beam splitter plate is adhered with the first prism and then adhered with the polarizer, the reflector is adhered with the first wave zone plate, and the collimator objective, the polarization beam splitter plate and the reflector are respectively adhered with the third prism. All the components of the optical path folding system are made of cheap and common glass K9 materials which can be purchased easily, the optical path folding system is compact and reasonable in structure, good in processing technology and simple in assembling process and achieves the aim of being light in integral design.

Description

technical field [0001] The invention relates to an optical path folding system based on a polarization beam splitter and a zone plate, and belongs to the technical field of photoelectric comprehensive observation and aiming. Background technique [0002] A conventional optical system becomes bulky and bulky as the field of view of the system increases. For example, in flight simulation training and individual soldier simulation training, it provides real-time GPS navigation, road conditions, combat conditions, targets and other information and combat command information transmission systems for pilots, drivers, guns and rocket launchers, etc. In the optical system with strict requirements on the structural size of the system, the huge volume and weight greatly restrict its application. Therefore, it is very necessary to develop a light and compact optical system to overcome the defects of the traditional optical system in this respect. Contents of the invention [0003] ...
