Abstract
This invention provides a kind of eye lens and a near-eye display system that uses this eye lens. This eye lens has a lightweight and is good to make aspherical figure. The eye lens is made up of a series of lens, which are made from plastic. The eye lens of this invention is made up from plastic, which is convenient to make aspherical figure. It simplifies the structure of optic system, and decreases the cost. The character is that the lens has lightweight and the production efficiency is high. The near eye display system that uses this eye lens has the character of lightweight and high production efficiency too.
Description
Technical field
The present invention relates to a kind of optical instrument, particularly relate to a kind of eyepiece and adopt the near-eye display system of this eyepiece.
Background technology
Nearly eye demonstration claims the helmet to show again, is a kind of mode of utilizing optical lens to realize the virtual demonstration of large-screen image.Near-eye display system generally comprises light source, illuminator, light valve and eyepiece etc.The principle of work of near-eye display system is: the light that light source sends projects on the light valve through after converging processing such as amplification, through the modulation of light valve, forms virtual image by eyepiece.
The eyepiece of existing near-eye display system uses glass material to make mostly, and its shortcoming is that eyepiece is very heavy, is unfavorable for the wear-type application, causes people's sense of fatigue easily; Glass material is difficult for making aspheric surface, and the design complexity of spherical glass eyepiece, the number of lens is many; The large-scale production difficulty of glass eyepiece is big, the cost height.
Summary of the invention
Technical matters to be solved by this invention provides a kind of eyepiece and adopts the near-eye display system of this eyepiece, and this eyepiece is in light weight, helps making aspheric surface.
The technical scheme that technical solution problem of the present invention is adopted is: eyepiece, comprise lens set, and described lens set adopts plastic material to make.
The invention has the beneficial effects as follows: eyepiece of the present invention adopts plastic material to make, and conveniently makes aspheric surface, has simplified the structure of optical system, has reduced cost, has characteristics in light weight, that production efficiency is high.The near-eye display system that adopts eyepiece of the present invention to make also has in light weight, the low and optical system characteristic of simple of cost.

Fig. 2 is the structural representation of embodiments of the invention 2.
Fig. 3 is the structural representation of embodiments of the invention 3.
Embodiment
Further describe the present invention below in conjunction with drawings and Examples.
The lens set of eyepiece of the present invention adopts plastic material to make very convenient like this making aspheric surface.
Above-mentioned lens set has two, can adopt two gummed lens set 1 and field lens 2, also can adopt lens combination 3 and field lens 2, and wherein, the effect of field lens 2 is to strengthen the visual field, comprises a diffraction surfaces in the described lens combination 3 at least.
Said lens group 3 can adopt biconvex lens group or plano-convex lens group.
Has an aspheric surface at least in above-mentioned two lens set.
Above-mentioned lens set is made by two or more material, can adopt PMMA, PC or other optical plastics.
The near-eye display system that adopts above-mentioned eyepiece to make comprises eyepiece, illuminator and micro display chip 4.Because the eyepiece that has adopted plastic material to make, therefore, near-eye display system of the present invention has also had in light weight, the low and optical system characteristic of simple of cost.
Embodiment 1:
As shown in Figure 1, it is a kind of reflective near-eye display system, light source 8 is imaged onto on the reflective micro display chip 4 through reflector 5, catoptron 6 and field lens 2, micro display chip 4 is evenly illuminated, light enters into the pupil 7 of human eye again from micro display chip 4 outgoing through field lens 2, two gummed lens set 1.Consider the minute movement the when individual difference of different crowd eyes and eyes are observed, the emergent pupil design of system wants big; Consider the needs that band eyes personage observes, eyepiece is that the distance of exit pupil of system is also wanted greatly to the distance of human eye pupil; In order to guarantee that the virtual image that near-eye display system shows has the preferable image quality, eyepiece need be corrected aberrations such as spherical aberration, coma, aberration, the curvature of field, distortion, astigmatism.
In the present embodiment, the field lens 2 in the system has adopted aspheric surface near the one side of eyes, and two gummed lens set 1 adopt PMMA and PC material, and field lens 2 adopts the PMMA material.
Embodiment 2:
As shown in Figure 2, micro display chip 4 adopts the micro display chip of transmission-type, and illuminator adopts the backlight illumination.
In the present embodiment, the two gummed lens set 1 in the system have adopted aspheric surface near the one side of eyes, and two gummed lens set 1 adopt PMMA and PC material, and field lens 2 adopts the PMMA material.
Embodiment 3:
As shown in Figure 3, eyepiece adopts lens combination 3 and field lens 2 to form, and micro display chip 4 adopts the autoluminescence chip, no longer needs other illuminator.
In the present embodiment, the field lens 2 in the system has adopted aspheric surface near the one side of eyes, and lens combination 3 has adopted diffraction surfaces near the one side of micro display chip 4, and field lens 2 adopts the PC material.
