Description

The optical mirror plane imaging device

The utility model relates to a kind of imaging device of optical mirror plane.It can be used as the apparatus for demonstrating and the advertisement apparatus for demonstrating of teaching demonstration device, gift, valuables (for example jewelry).

As everyone knows, in the several centuries in the past, people have designed many optical devices, and it utilizes the combination of concave mirror, mirror and convex lens, in order not have screen, do not have frosted glass or similarly to produce real image under the help of displayer in the space, but their great majority are proved to be to be difficult to realize.

Yet, if can realize the optical mirror plane imaging device, but can bring many benefits, for example be used for representing the real image of jewelry, make the beholder can from real image, comprehend the aesthetic feeling of actual jewelry, but hand but at all can not touch the body of jewelry, like this, can prevent its people's pilferage.

The purpose of this utility model provides a kind of optical mirror plane imaging device, and it can form series of products, and for example: teaching demonstration device, gift, valuables exhibition show device and advertising device.

Realization of the present utility model is according to being: utilize a pair of concave mirror, their concave surface is staggered relatively, wherein have on the concave mirror optical aperture is arranged, combine, can produce real image being placed on two objects between the minute surface with another piece concave mirror, and cast out by the aperture, picture can appear at the space at place, aperture, perhaps just in time on the aperture, and perhaps can be under the aperture, real image can be littler than object, also can be bigger than object.Fig. 1 be the cross section of a pair of concave mirror of this device and the formed real image 3 of light that sends from the object 3 of unrolling and viewing a scroll painting ' index path.Among Fig. 1 11, the 21st, concave mirror, the 3rd, the object of unrolling and viewing a scroll painting, with arrow represent the to unroll and view a scroll painting orientation of object 3, light 33,34 sends from the object 3 of unrolling and viewing a scroll painting, incide the reflecting surface of concave mirror 11, reflected by concave mirror 21 again, these convergences of rays at last near the center pit 12 of concave mirror 11, become real image 3 ', as 3 ' counter-rotating about being with the object 3 of unrolling and viewing a scroll painting, as shown by arrows.

From the above, the utility model is to realize like this, it comprises shell body and is arranged at the interior object of unrolling and viewing a scroll painting of this shell body, be characterized in, this shell body comprises upper shell and lower house, and their inside surface is a pair of upper and lower concave mirror of putting in opposite directions with optical axis, and this upper recess surface mirror is formed this optical axis surfaces of revolution by a curve; This concave surface mirror forms the surfaces of revolution of this optical axis, and spaced apart to the concave surface of this upper recess surface mirror, and the concave surface of this concave surface mirror is towards the concave surface of this upper recess surface mirror; Also on this upper half-shell, offer a center pit.

Further, fill up the transparent body or between this upper and lower concave mirror, establish a lamina of septum pellucidum between this upper and lower concave mirror.Can avoid losing of display material like this, also can between this upper and lower concave mirror, lighting source be set.Make it have innervation in order better to represent the object of unrolling and viewing a scroll painting, the utility model also is provided with removable or rotating placing part near the optical axis of this concave surface mirror, and this unrolls and view a scroll painting placing object on this placing part.

The utility model has the advantages that:

(1) can be used as maths demonstration,, vividly demonstrate the imaging of object, have very great help improving teaching efficiency in conjunction with the teaching of geometrical optics in the physics.

(2) small-sized this device through suitable packing, can be made gift or toy, and it is better especially to make tourist souvenir.

(3) large-scale this device adds that rotation and light annex can do the advertisement demonstration.

(4) this device can be demonstrated in valuables shops such as jewelry or scientific exhibit.

Accompanying drawing of the present utility model is simply described as follows:

Fig. 1 is a light path principle synoptic diagram of the present utility model.

Fig. 2 is a housing exploded perspective synoptic diagram of the present utility model.

Fig. 3 is the unroll and view a scroll painting synoptic diagram of thing of lower house device of the present utility model.

Fig. 4 is an enforcement illustration of the present utility model.

Fig. 5 is an another kind of structural representation of the present utility model.

Below, we will provide better embodiment of the utility model according to Fig. 1～Fig. 5, so that structure of the present utility model is described, feature and effect enable better to understand the utility model rather than are used for limiting claim protection domain of the present utility model.

See also Fig. 2, Fig. 3 and Fig. 4, as shown in the figure, the utility model comprise the shell body 1 that constitutes by upper shell 1 and lower house 2 ', and be placed in this shell body 1 ' interior object 3 of unrolling and viewing a scroll painting, on being somebody's turn to do, lower house 1,2 inside surface is to have on optical axis a pair of, concave surface mirror 11,21, they are being put relatively, they can be by the polishing metal, silver-plated metal transparent silver-plated (or chromium plating) material as plastics or glass, perhaps any other high reflecting surface, as long as can produce real image, the type of the curve of this two minute surface can be a para-curve, spherical curve, ellipsoid curve and near the curve of these types, this upper shell 1 is offered a center pit 12, this two concave mirror 11,21 is staggered relatively, and bottom this concave surface mirror, lay the object 3 of unrolling and viewing a scroll painting, in the present embodiment, this object 3 of unrolling and viewing a scroll painting is a jewelry, the light path of its formation as shown in Figure 1, this object 3 of unrolling and viewing a scroll painting just on the space of this center pit 12, form a real image 3 ', the beholder can see the top of this jewelry on these center pit 12 spaces like this, bottom and edge all around, though do not contact this object 3 of unrolling and viewing a scroll painting, but can be from this real image 3 ' and can make visual investigation to this object 3 of unrolling and viewing a scroll painting, in the present embodiment, in order to prevent that other people from stealing this jewelry, can be on this, concave surface mirror 11, fill up the transparent body (not shown) in 21 spaces that surrounded or on this, concave surface mirror 11, set firmly a lamina of septum pellucidum (for example glass plate) (not shown) between 21.

In order to make real image 3 ' have innervation, can near the optical axis of this concave surface mirror 21, settle a rotating placing part 22 as shown in Figure 5.Drive object 3 rotation of unrolling and viewing a scroll painting of laying thereon by motor (not shown) transmission when it like this, thus can obtain sporty real image 3 '.Also can in the space that upper and lower concave mirror 11,21 surrounds light source (not shown) be set, like this, the utility model more can be suitable as advertising device.
