目镜 eyepiece

[0001] 技术领域 [0001] Technical Field

[0002] 本发明涉及一种目镜,特别是一种用于头盔式显示器中的目镜,属于光学技术领域。 [0002] The present invention relates to an eyepiece, in particular a helmet for the display of the eyepiece, which belongs to the field of optical technology.

[0003] 背景技术 [0003] BACKGROUND OF THE INVENTION

[0004] 头盔式显示器(Head Mounted Display)是近年来显示领域的热门产品,用于虚拟现实和增强显示的头盔图像显示装置取得了长足的发展。 [0004] HMD (Head Mounted Display) is a popular product in recent years, the field for virtual reality and augmented helmet image display device which has made great strides. 由于头盔显示装置安装在观察者的头部,因此它必须结构紧凑、重量轻,以减轻观察者的负载。 Since the helmet mounted display device of the head of an observer, it must be compact, light weight, in order to reduce the load on the observer. 头盔显示器主要由三个部分构成:显示部件、光学镜头和头盔,要减轻重量,光学系统是关键,但光学系统的紧凑型与头盔显示器对光学系统成像质量的要求之间存在一定的矛盾。 HMD is mainly composed of three parts: a display section, an optical lens and a helmet, to reduce weight, the optical system is the key, but there is a certain conflict between the optical system compact and image quality requirements for HMD optical system. 对于头盔显示器而言,要求光学系统可以做到比较大的视场和出瞳直径,因为观察视场的增加,观察范围也会增加,观察者才能更全神贯注的观察优质的动态图像,出瞳直径增加可以保证头盔适应不同瞳距的观察者,而不必调整头盔的瞳距,同时允许观察者在观察过程中眼珠能随意转动而不至于丢失图像。 For helmet mounted display, the optical system can be done requires a relatively large field of view and the exit pupil, because the increase in the observation field, will increase the range of observation, the observer can observe a more concentrate quality moving image, the pupil diameter We can guarantee the helmet adapted to increase the observer of different IPD, IPD without having to adjust the helmet, while allowing a viewer eyes can rotate freely during observation and the image is not lost. 但光学系统的视场、出瞳直径、焦距三者之间有相互制约的关系,同时达到大视场,大出瞳直径和短焦(即系统的紧凑化)并不容易。 However, the field of view of the optical system, the pupil diameter, there is the focal length of the three mutual checks, while achieving wide field of view and large exit pupil diameter and a short focal (i.e., compact system) is not easy. 另外,像面的照度的均匀性也对使用头盔显示器观看时的观看质量有明显影响,光学系统需要兼顾上述多种需求。 Further, as the surface illumination uniformity also had a significant effect on viewing quality when viewing the display using the helmet, the optical system needs to take into account the various needs described above.
