Description

A kind of wear-type 3D viewing glasses

Technical field

The utility model relates to a kind of viewing glasses, especially relates to a kind of wear-type 3D viewing glasses.

Background technology

People is when observing external object, and right and left eyes respectively sees the left side of three-dimensional scene and the details on right side, is formed with the two-dimensional image that two of horizontal parallax are similar on the retina, and these two two-dimensional images, through reproduction, just define three-dimensional image.Three-dimensional film is exactly the process that simulation human eye 3-D view is formed, and first the single eye images of right and left eyes is recorded respectively, by projector and phase

The three-dimensional projection equipment of answering, allows spectators' right and left eyes see corresponding single eye images respectively, then reappears into 3-D view by brain.Technically, the right and left eyes that the two picture presentation in left and right also mirrors spectators respectively will be realized exactly.

There are following three kinds of basic projection methods at present:

(a) optical spectroscopy: only a kind of electromagnetic wave of high frequency, the light vector of natural light is evenly distributed in any direction.Utilize optical medium that the light vector of any direction is divided into two parts according to certain rules, transmit the method for right and left eyes image information respectively, be called optical spectroscopy.What linear polarization glasses and circular polarization glasses utilized is exactly optical spectroscopy.

(b) color seperation: visible ray is the appreciable part of human eye in electromagnetic wave spectrum, and the spectrum of visible ray does not have accurate scope; The appreciable electromagnetic wavelength of eyes of common people is greatly between 400-700 nanometers.Utilize optical medium light beam by different spectral region separately, transmit the method for right and left eyes image information respectively, be called color seperation.What red indigo plant (green) glasses of use in the past and the Doby glasses of application now utilized is exactly color seperation.

(c) time-sharing approach: the right and left eyes image of stereoscopic picture plane is carried out alternately switching fast, and the glasses of viewers wear also carry out corresponding synchronism switching simultaneously, and this countershaft on time alternately transmits the method for right and left eyes image information, is called time-sharing approach.Film three-dimensional film is adopt mechanical system to complete above-mentioned functions period, and on digital 3D film, is then that application liquid crystal shutter glasses reach same object.

New digital 3D motion picture projection technique is as follows:

(a) circular polarization technology: circular polarization technology is that online polarization based develops.Circular polarizer is made up of one piece of linear polarizer and one block of quarter-wave plate.A kind of anisotropic medium of quarter-wave plate is made, and the light through linear polarizer is converted into circularly polarized light by it.Polarization direction due to circularly polarized light is regular being rotating, and is divided into left-hand polarization light and right-handed polarized light, and mutual interference is very little, and therefore its logical light characteristic and light-blocking property be not substantially by the impact of the anglec of rotation.This just makes there has been qualitative leap than linear polarization technology on viewing effect.

(b) optical filtering technique: optical filtering technique belongs to the application of color seperation, similar red blue glasses, but its technical merit improves much than red blue glasses.New optical filtering technique not only increases light efficiency, the more important thing is that it can see gorgeous colour picture.

(c) liquid crystal shutter optometric technology: what liquid crystal shutter optometric technology adopted is time-sharing approach viewing stereopsis.Liquid crystal be a kind of between solid and liquid, there is the organic compound of systematicness molecules align, generally the most frequently used liquid crystal is nematic liquid crystal, molecule present situation is elongated clavate, under different current electric fields effect, liquid crystal molecule can do rules rotating 90 ° arrangement, produce the difference of penetrability, so when external power connecting and disconnecting, resistance light and logical optical phenomenon can be produced.This characteristic of liquid crystal is applied on 3D glasses, just can produces liquid crystal shutter glasses.The eyeglass of liquid crystal shutter glasses seems the two fan small windows controlling opening and closing respectively.When same projector is alternately play right and left eyes picture, by the synchronous opening/closing function of liquid crystal glasses, like this when showing left picture, left eyeglass lens opens logical light, and right eye eyeglass is closed, and spectators' left eye sees left picture, and what all can't see right eye.Equally, when putting right picture, right eye can see right picture, and left eye can't see picture, allows right and left eyes see left and right picture separately respectively with speed faster like this, thus produces stereoeffect.

Existing 3D eyeglass design is common frame type and clip type, is specially:

1. common frame spectacle

Namely common frame spectacle is replace common eyeglass with 3D glasses specialized lens, mainly uses polarized lenses.Because picture frame generally uses acetate fiber or epoxy resin etc., therefore it is with low cost.But this kind of pattern is very unfriendly for the spectators of wearing spectacles, and the eyeglass itself due to 3D glasses can do nothing to help spectators and corrects defects of vision, so spectators need to wear two pair of glasses simultaneously, cause the viewing of near-sighted spectators to be experienced not good, greatly reduce viewing interest.

2. clip type

Clip type 3D glasses viewing glasses are roughly divided into two parts, eyeglass, support.Clip type be aim at wearing spectacles spectators designed by.When wearing, by the nose support place of support clamp at the glasses of spectators oneself, make its entirety fit in glasses, reaching does not need to change glasses and just can experience splendid viewing effect.But the shortcoming of this kind of design is that it is only applicable to the spectators worn glasses, and the cost of movie theatre therefore can be caused to increase, therefore normal cinema generally can not specially be equipped with this type of glasses.
