Description
Technical field
The present invention relates to a kind of eyepiece, particularly a kind of eyepiece that is used for helmet-mounted display belongs to optical technical field.
Background technology
Helmet-mounted display (Head Mounted Display) is the hot product that shows the field in recent years, is used for virtual reality and strengthens the helmet image display device that shows having obtained significant progress.Because helmet mounted display device is installed in observer's head, so it must compact conformation, in light weight, to alleviate observer's load.Helmet Mounted Display mainly is made of three parts: display unit, optical lens and the helmet, weight reduction, and optical system is crucial, but has certain contradiction between the requirement to optical system imaging quality of the compact of optical system and Helmet Mounted Display.For Helmet Mounted Display, require optical system can accomplish bigger visual field and exit pupil diameter, because observe the increase of visual field, range of observation also can increase, the observer could more absorbed observation high-quality dynamic image, the exit pupil diameter increase can guarantee that the helmet adapts to the observer of different interpupillary distances, and needn't adjust the interpupillary distance of the helmet, allows observer's eyeball in the observation process arbitrarily to rotate simultaneously and is unlikely to lose image.But the relation of mutual restriction is arranged between the visual field of optical system, exit pupil diameter, the focal length three, reach big visual field simultaneously, big exit pupil diameter and short burnt (being the densification of system) also are not easy.In addition, the viewing quality the when homogeneity of the illumination of image planes is also watched the use Helmet Mounted Display has a significant effect, and optical system need be taken into account above-mentioned multiple demand.
Summary of the invention
In view of above-mentioned requirements, the present invention proposes the very eyepiece of compactness, very light weight of a kind of structure, be used for Helmet Mounted Display, with the image amplification of helmet miniscope spare demonstration and through being positioned at the eyes imaging at diaphragm place.This eyepiece exit pupil diameter is greater than general eyepiece, and distance of exit pupil is long, and field angle is big, adopts miniscope to guarantee compact conformation, so focal length is little and F/# is little; And eyepiece of the present invention is as Fang Yuanxin, and the incident angle of all visual field chief rays on image planes all less than 4 degree, can guarantee that illuminance of image plane is more even, is beneficial to human eye and watches.

Preferably, each focal length of described eyepiece system also satisfies following (4)～(6) relational expression, to obtain better imaging effect.
(4)1.2＜f12/fw＜1.5
(5)2＜|f34/fw|＜3.5
(6)0.85＜f15/fw＜1.3
Preferably, first lens of above-mentioned eyepiece and second lens can be positive lens, and third and fourth lens are just constituting-bearing the cemented doublet of form.
Preferably, the 5th lens are positive lens, and the 6th lens can be positive lens or negative lens.
Preferably, the emergent pupil of described eyepiece system is less than 8 or equal 8.
The invention still further relates to a kind of Helmet Mounted Display that uses above-mentioned eyepiece, in human eye, human eye is positioned at the diaphragm place to be observed with the image imaging that shows on the LCD, and wherein LCD is to fail to grow up in 3 inches in the diagonal angle of miniscope, usually less than 1 inch.
Beneficial effect
Eyepiece of the present invention has the advantage of compact conformation, light weight; The eyepiece exit pupil diameter is greater than general eyepiece, and distance of exit pupil is long, and field angle is big, and focal length is little and F/# is little; Eyepiece is as Fang Yuanxin, and the incident angle of all visual field chief rays on image planes all less than 4 degree, can guarantee that illuminance of image plane is more even, is beneficial to human eye and watches.
