Description
Technical field
The utility model relates to the field of optical for watching stereotelevision, in particular to stereotelevision multiplying arrangement.
Background technology
Stereotelevision is a kind of television system of the real space relation that can simulate actual scene.Mainly contain at present the method that following several stereotelevision is watched:
1, time division type: i.e. active-shutter.Time-sharing procedure transmits right and left eyes image by turns with certain speed, and video picture end shows in turn the image of two of left and right on a screen.Beholder need wear secondary liquid crystal shutter glasses, by a switch control of synchronizeing with transmitting terminal, and in the time that left-eye image occurs, the liquid crystal printing opacity of left eye, the liquid crystal of right eye is light tight; On the contrary, in the time that eye image occurs, only has the liquid crystal printing opacity of right eye; Final left and right two eyes can only be seen image separately.
2, complementary colors: claim again aberration formula 3D technology, principle of work is to demonstrate respectively for left and right two and observe the image of seeing by two kinds of complementary colors on screen.The image of for example delivering to left eye only has redness; The image of delivering to right eye only has blueness.While watching, will wear tinted glasses, make left eye can only see red image, right eye can only be seen blue image, is fused into a stereo-picture in brain.
3, polarized light type; Two images of stereogram are modulated into respectively mutually perpendicular two kinds of polarized lights and are exported by same screen, and spectators only need wear corresponding polarised light glasses can see stereopsis.
4, observation mirror: two image spaced apart of stereogram are on screen, and two groups of optical mirror translation two eye sight lines for observation mirror, see secondary left and right two anaglyph together, realize watching of stereo-picture.While watching stereotelevision due to use observation mirror, horizontal parallax image is simultaneously displayed on the display screen of TV, and the image of watching only has screen size half, uses observation mirror to watch stereotelevision, and the image of watching is little.
5, raster pattern: raster pattern is that bore hole formula need just can not see stereopsis by any servicing unit.Shortcoming is that viewing location is had to strict restriction.
Wherein time division type, polarized light type and raster pattern need be used special three-dimensional display, and aberration formula effect is the poorest, and observation mirror sees that stereographic map effect is best, but the image of seeing only has screen half size.And the stereopsis that above several modes are seen equates all do not possess image amplifying power at most with screen.
Utility model content
The purpose of this utility model is to provide a kind of stereotelevision multiplying arrangement, to solve the above problems.
A kind of stereotelevision multiplying arrangement is provided in embodiment of the present utility model, has comprised two lens barrels; Described in each, lens barrel comprises object lens, eyepiece and relay system; Described relay system is being for realizing after image rotation, and can change that to make the angle of itself and the former direction of propagation by the direction of propagation of object lens primary optical axis light be 1 °～30 °.
The stereotelevision multiplying arrangement that the utility model embodiment provides, compared with observation mirror of the prior art, it comprises two object lens, two eyepieces and two relay systems.While using this stereotelevision multiplying arrangement to watch stereotelevision, the image of stereotelevision is injected from object lens, through the image rotation of relay system and after making the Yu Yuan direction of propagation, its direction of propagation change 1 °～30 °, inject in human eye from eyepiece, image is respectively after object lens and eyepiece, can be exaggerated certain multiplying power, make stereopsis that beholder sees be greater than the size of half display screen.Use this stereotelevision multiplying arrangement to watch stereotelevision, the image of watching is large, and uses this stereotelevision multiplying arrangement to watch stereotelevision, does not need special three-dimensional display, and viewing effect is good.
