摘要	Augmented reality helmet mounted display (HMD) requires two or more focal planes to display pictures at different focal lengths, which not only enhances the depth of field effect, but also reduces the visual conflict and discomfort caused by a single focal plane. A relatively traditional solution is to use two separate picture generation units (PGUs). However, it increases the cost, reduces the reliability, and is bulky. We design a new structure using a single PGU and a single free-form surface prism. By setting two separate areas on the PGU and making one of the image areas relayed to the new remote position through two flat mirrors, we achieve a bifocal surface display. Finally, a HMD optical system is designed, which possesses a field-of-view angle of 1816, an exit pupil diameter of 8 mm, a working wavelength of 540640 nm, an exit pupil distance greater than 15 mm, and two focal lengths of 95.2 mm and 35.2 mm. 2020, Chinese Lasers Press.
