“…However, the optical system itself has properties that require a long enough optical path distance for the light to travel through the overall optical system if the image of the microdisplay is to be magnified [49,50]. On this basis, if one wants to optimize the volume of the virtual reality headset display, one requires an increase in the number of light reflections in the optical system and an enhancement of the effective optical path distance of the light [51,52]. Therefore, based on this design concept, researchers have developed an optical folding scheme (Pancake lens) that combines refractive optics or polarization theory with a lens array.…”

Driven by the rapid innovation of science and technology and industrial manufacturing technology, virtual reality display technology has developed rapidly. At present, the application of virtual reality display technology is expanding in many fields such as military, medical, aviation and education. This paper analyzes the imaging principle of the human vision system and the optical performance requirements of VR heads-up display, summarizes the current design scheme of VR heads-up optical imaging system, focuses on the principle and index parameters of each optical system, and compares the advantages and disadvantages of different schemes. The development prospects and directions of virtual reality headset displays are also prospected.
