用于近眼显示的目镜光学系统及头戴显示装置制造方法及图纸

用于近眼显示的目镜光学系统及头戴显示装置。目镜光学系统包括第一透镜(L1)、反射单元(P)、第二透镜(L2)和第三透镜组(G3)；第二透镜和第三透镜组的光轴共轴，且垂直于微型图像显示器(I)；第二透镜和第三透镜组的光轴经过反射单元反射后与第一透镜的光轴共轴；第三透镜组至少包括第三透镜(L3)；第二透镜和第三透镜为光学非球面面型，第一透镜为设置于反射单元与人眼观察侧之间的唯一透镜；第三透镜组进一步包括靠近微型图像显示器的第四透镜(L4)。这种目镜光学系统具有结构紧凑、小尺寸、高光学分辨率等优点，可使头戴显示装置达到最佳的视觉体验。

Eyepiece optical system and head display device for near eye display

Eyepiece optical system and head display device for near eye display. The eyepiece optical system consists of a first lens (L1), a reflecting unit (P), a second lens (L2) and a third lens group (G3); the optical axis of the second lens and a third lens group is coaxial and perpendicular to the micro image display (I); the optical axis of the second lens and a third lens group is coaxial with the optical axis of the first lens after reflection by the reflecting unit; and the third transmission. The lens group comprises at least a third lens (L3); the second lens and the third lens are optical aspherical, the first lens is the only lens set between the reflecting unit and the human eye observation side; and the third lens group further comprises a fourth lens (L4) close to the micro image display. This eyepiece optical system has the advantages of compact structure, small size, high optical resolution, etc. It can make the head-mounted display device achieve the best visual experience.
