Abstract
The utility model relates to a display device for showing three-dimensional image in the space. An article can be projected to a spherical concave mirror in the mode of axial ray by utilizing the principle that the axial parallel light can be converged by the spherical concave mirror, and then the convergent light which is reflected by the spherical concave mirror can be reflected to one side of an optical axis by a semi-concave and semi-reflecting plane mirror, so that a floating image in the space can be formed. The utility model is characterized in that: a projecting apparatus is positioned at one end of a box body; the spherical concave mirror is arranged at the other side of the box body; the semi-concave and semi-reflecting plane mirror is arranged at the position between the projecting apparatus and the spherical concave mirror and is formed into an angle with the optical axis, and the semi-concave and semi-reflecting plane mirror can be shaped at one side of the optical axis of the spherical concave mirror.
Description
The utility model relates to a kind of exhibiting device that shows 3-D view in the space.
For many years, for experiencing 3-D view, people have carried out unremitting effort, have obtained some achievements; As the patent No. is 97121529.3 the device of 3-D view " show ", by polarized light and polarising glass, and " three-dimensional " image that the psycho-visual that utilizes the parallax of people's right and left eyes to form forms on screen.Its image is not real " three-dimensional ", and uses very inconvenient.
The purpose of this utility model provides a kind of article can displayings in the space three-dimensional mode, and is easy to use, can with the naked eye observe directly the device of 3-D view clearly.
Space three-dimensional image shows device described in the utility model, the principle of utilizing sphere matrix catoptron paraxial directional light can be converged, with the mode of article with paraxial rays, project on the sphere matrix catoptron, converge the side that light reflexes to optical axis with semi-transparent semi-reflecting level crossing with what sphere matrix mirror reflects was returned again, be formed on the image that floats in the space.
Concrete structure is: in a casing, an end is provided with the projection arrangement that produces the article paraxial rays; The other end is provided with converging after the reflection of article paraxial rays, forms the sphere matrix catoptron of spatial image; Between projection arrangement and sphere matrix catoptron, place a semi-transparent semi-reflecting level crossing that three-dimension space image is taken shape in sphere matrix mirror optical axis one side at angle with optical axis.
Grenade instrumentation can be used the shot-light irradiating item with electron radiation, and the reflected light of article is projected on the sphere matrix catoptron; Also can utilize projector that image projection is arrived sphere matrix catoptron.The light of projection passes semi-transparent semi-reflecting level crossing in the paraxial rays mode and projects on the sphere matrix catoptron, return through converging back reflection, to converge the side that light reflexes to sphere matrix mirror optical axis again by semi-transparent semi-reflecting level crossing again, just can observe directly clearly the space three-dimensional image easily in a side of optical axis.
Grenade instrumentation can be located immediately on the sphere matrix mirror optical axis, also can place a plane mirror between grenade instrumentation and semi-transparent semi-reflecting level crossing, projection arrangement is positioned over a side of sphere matrix mirror optical axis; The optical axis of plane mirror and sphere matrix catoptron has an angle, and its angle is preferably 45 degree.
Semi-transparent semi-reflecting level crossing must be positioned on the optical axis of sphere matrix catoptron, its plane and sphere matrix mirror optical axis have an angle, its angle is preferably 45 degree, and the higher one side of semi-transparent semi-reflecting level crossing transmissivity reflects higher one side towards sphere matrix catoptron towards light source direction.
The curved surface of sphere matrix catoptron also can adopt parabola.
Article in the utility model can be material object, model or image; Can make it produce motion by means of mechanical mechanism for material object or model, increase attractive force.
The advantage of the utility model space three-dimensional image shows device is: any other instrument need not be used, space three-dimensional image clearly can be with the naked eye observed directly, and simple in structure, use very convenient.
Now be described in detail an example of this utility model as follows in conjunction with the accompanying drawings:
Fig. 1 is the utility model space three-dimensional image shows schematic representation of apparatus
(1) is casing among the figure, and (2) are shot-light, and (3) are article, and (5) are semi-transparent semi-reflecting level crossing, and (6) are the sphere concave mirror, and (7) are optical axis, and (8) are the space three-dimensional image.
The shot-light (2) and the article (3) that are positioned at casing (1) one end have been formed projection arrangement, several shot-lights are radiated on the article (3) uniformly, the partial reflection light that article (3) produce, pass the semi-transparent semi-reflecting level crossing (5) that becomes miter angle with optical axis, project on the sphere matrix catoptron (6) that is positioned at the casing other end; Converge the formation image through sphere matrix catoptron (6) reflection again and converge light; Image converges the side of light through semi-transparent semi-reflecting level crossing (5) reflection deflection optical axis (7), by the opening on the casing (1), and the space three-dimensional image (8) that forms in casing (1) outside.
The reflected light transfer route in article (3) centre will be as far as possible near optical axis (7), and the reflected light that as far as possible makes article projects sphere matrix catoptron (6) in the mode of paraxial rays, can obtain space three-dimensional image (8) clearly like this.
