Abstract
The invention discloses a kind of optical presentation system schemes using non-critical Amici prism.It is high and convenient for production to export image quality, not high to equipment and material requirements, system application environment is wider.
Description
Technical field
The present invention relates to a kind of optical presentation system schemes, more particularly, to a kind of optics using non-critical Amici prism
Display system scheme.
Background technology
In using the optical presentation system that LCOS is image source, PBS polarization splitting prism cooperatings are generally required,
Middle PBS polarization beam splitters generally require accurate plated film tens layers, and production is inconvenient, and the use of PBS polarization beam splitters has many restrictions,
Higher image quality can not be obtained in all application environments.
Invention content
The present invention proposes a kind of optics using non-critical Amici prism for the optical presentation system that LCOS is image source
Display system scheme, this scheme is convenient for production, and display effect is good, can be applied in various environment.
The invention is realized by the following technical scheme：
A kind of optical presentation system scheme using non-critical Amici prism, including lighting part, image source, imaging moiety.
System composed structure is：System is by based on two pieces of non-critical Amici prisms, two non-critical Amici prisms are arranged side by side
Arrangement, can be installed with any rotation, and one is used for lighting part, and one is used for imaging moiety.The part of all parts it
Between have enough dielectric gaps, whole system sealing completely cuts off extraneous air.
Here is the detailed description of each part：
Lighting part：Including collimated light source, multiple optical filters, polarizing film, a non-critical Amici prism.
Wherein light source is using the approximately parallel area source that emits beam, in addition appropriate optical filter adjusts illumination uniformity matter
Amount adjusts lighting colour quality.
It the polarization direction of the polarizing film of lighting part can be with P or S.
Image source part：Using reflective LCoS image source.
Non-critical Amici prism feature：It is the Amici prism simply produced, splitting ratio can not known, and the polarization of light splitting is special
Property can not also determine that two non-critical Amici prisms need not be the same, and size and shape does not have particular/special requirement.
There are a piece of polarizing film, the polarization side of polarization direction and lighting part polarizing film among two non-critical Amici prisms
To vertical.
Imaging moiety：Including a non-critical Amici prism and the reflective collimating eye-piece of a piece of or two panels.
Reflective collimating eye-piece, when using two panels, two eyepieces are mounted on the two neighboring side of non-critical Amici prism.
The focal length of two reflective collimating eye-pieces is equal to or more than the sum of the length of side of two non-critical prism cross-sections.
The present invention operation principle be：
The less parallel light that lighting part light source is sent out passes through optical filter, and polarizing film becomes uniform parallel polarized light.Polarised light
Into first non-critical Amici prism, non-critical Amici prism will be above the light reflection to LCOS of part.
When pixel is lit on LCOS, the light for reaching LCOS is reflected, and the light reflected becomes polarization state
Change.
The light reflected is non-at this time into the non-critical Amici prism of imaging moiety by another polarizing film
Light is divided into mutually perpendicular two-way by stringent Amici prism, and two-way light respectively enters two reflective collimating eye-pieces, light
It is come out by eyepiece collimated reflected.
Light is directed through non-critical Amici prism output all the way, is exported after the reflection of non-critical Amici prism all the way.
When using two panels collimating eye-piece, center will be aligned, and two-way light image is made to overlap, and light can be made using maximization.Using a piece of
When collimating eye-piece, the output imaging of single channel light, this scheme assembles more convenient.
The beneficial effects of the invention are as follows：It is high and convenient for production to export image quality, it is not high to equipment and material requirements,
System application environment is wider.
Description of the drawings
Fig. 1 is the exemplary block diagram of the present invention.
Specific implementation mode
Technical scheme of the present invention is further described below in conjunction with the accompanying drawings.
As shown in Figure 1：5,6 be two non-critical Amici prisms, and two Amici prisms can be by central shaft（7）Rotate random angle
Degree installation.1 is collimated light source, and 2 be optical filter, and 3 be polarizing film, and 4 be reflective LCoS image source, and 8,9 be reflective collimation mesh
Mirror, 10 be a piece of polarizing film.
There are enough dielectric gaps, whole system encapsulation process and outside air medium in figure between all parts
Isolation.
Point light source is become less parallel light by lens and comes out by light source 1 in figure.Light passes sequentially through uniformly from top to bottom
Optical filter（2）, polarizing film（3）, into first non-critical Amici prism（5）, light is uniform polarised light at this time.
Non-critical Amici prism（5）Some light is reflected into LCOS（4）, work as LCOS（4）Light when upper pixel is lit
It is reflected and, the polarization of light state reflected changes.
The light reflected passes through polarizing film（10）, into second non-critical Amici prism（6）.Second non-critical
Amici prism（6）Light is divided into two-way, all the way upwards, all the way to the left, two-way light respectively enters reflective collimating eye-piece（8,
9）.
Into after reflective collimating eye-piece, two-way light is come out by eyepiece collimation back reflection, and upper road light passes through second
To lower output after being reflected to lower output image light, left light by second non-critical Amici prism after non-critical Amici prism
Image light.
The wherein reflective collimating eye-piece of two panels needs centring, it is ensured that two-way optic biradial overlaps, just exportable same
A image.
If removing arbitrary a piece of reflective collimation mesh, image is exported in the same old way, and only brightness reduces.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
It encloses and is defined, under the premise of not departing from design spirit of the present invention, technical side of the those of ordinary skill in the art to the present invention
The various modifications and improvement that case is made should all be fallen into the protection domain of claims of the present invention determination.
