Abstract

The utility model discloses a focusing aligning apparatus for a stereoscopic synthesizer. Light which is projected on photosensitive materials is reflected to a ground glass screen by a reflector to be focused. The utility model adopts a cross wire on the ground glass screen to align. The image on the ground glass screen is collected by a CCD camera and is amplified on a monitor screen to be aligned with high precision. A focusing aligner is attached to an alignment plate by a strong magnet to be positioned. The optical length from the focusing aligner to a focusing screen is equal to the optical length from the focusing aligner to the surface of photosensitive material emulsion. Thus, focus adjustment and alignment of image can be completed on the alignment plate which is higher than a film bearing station.

Description

Stereopsis is synthetic with the focusing aligner

The utility model relates to a kind of photography focusing mechanism, the focusing aligner of the synthetic usefulness of particularly a kind of stereopsis.

At present, the common amplification focusing device utilization reflection light path and the principle of incident equivalent optical path can only be used on the focusing plane, and after the focusing point departs from the picture center, because the incident light projectional angle is excessive, can't imaging.Three-dimensional synthesizer is carried out on photosensitive material and has been covered grating, can't visually focus.The synthesizer alignment sheets is being held on sheet closes mostly, makes alignment surface and photosensitive emulsion planar separation alignment point again outside the picture center of being everlasting, and can't aim at common amplification focalizer focusing.

The purpose of this utility model is to provide a kind of not aplanatism focusing aligner, can finish the image focusing for three-dimensional synthesizer and aim at picture.

The purpose of utility model is achieved in that

A kind of stereopsis is synthetic with the focusing aligner; Be by matrix, front reflective mirror, cover glass, formations such as focusing frosted glass; It is characterized in that: the matrix bottom surface is placed on the last plane of synthesizer alignment sheets, the front reflective mirror will incide light on the photosensitive material and reflex on the frosted glass plane and focus on, and the reflective mirror plane of focusing device equates with the angle on frosted glass plane and synthesizer wafer-supporting platform plane; Make the difference of reflective mirror equal on the alignment sheets plane to the light path C on photosensitive material emulsion plane to the light path A of frosted glass frosting and reflective mirror to the light path B of matrix bottom surface:

C＝A-B； A＝B+C

Be the equivalent optical path of reflective mirror to frosted glass sand face and photosensitive material emulsion plane.

---describedly on the frosted glass frosting, print cross curve.

---the material of described alignment sheets is a ferromagnetic plate, in the matrix of focusing device strong magnet is set, and relies on the suction of magnet, promptly can move the focusing aligner artificially, and the aligner that can prevent from again to focus moves on alignment sheets voluntarily.

---described CCD camera and the display of also including.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the amplification focusing device schematic diagram of existing art.

Fig. 2 is the schematic diagram and the user mode figure of the utility model focusing aligner.

Among the figure: 1. matrix; 2. front reflective mirror; 3. cover glass; 4. focusing frosted glass; 5.CCD camera; 6. strong magnet; 7. monitor; 8. grating; 9. photosensitive material, 10. wafer-supporting platform; 11. alignment sheets;

α. projection light scope allowable; M. effective projection light; N. invalid projection light.

Referring to Fig. 2; the focusing aligner is made up of elements such as matrix 1, front reflective mirror 2, cover glass 2, focusing frosted glass 4; the bottom surface of matrix 1 is placed on the last plane of synthesizer alignment sheets 11, and front reflective mirror 2 will incide light on the photosensitive material 9 and reflex on frosted glass 4 planes and focus on.The reflective mirror plane of focusing device equates with the angle on frosted glass plane and synthesizer wafer-supporting platform 10 planes, makes the difference of reflective mirror to the light path A of frosted glass frosting and reflective mirror to the light path B of matrix bottom surface equal on the alignment sheets 11 plane to the light path C on photosensitive material 9 emulsion planes:

C＝A-B

Can obtain A=B+C thus and be reflective mirror 2 to frosted glass frosting 4 and equivalent optical path to photosensitive material 9 emulsion planes, therefore can be on frosted glass accurate focusing.

The utility model is printed cross curve on frosted glass 4 frostings, in the time of the alignment point on the drawing promptly can being guaranteed the compound stereoscopic photo by reticle alignment, the alignment point of the three-dimensional picture of each width of cloth overlaps mutually at every turn.

The utility model increases the size of focusing device reflective mirror and cover glass, thereby can increase the incident angle of throw light, realizes the full frame aligning.With CCD camera 5 image on frosted glass 4 screens is shown on the monitor 7 simultaneously and aims at, thereby can improve alignment precision.In addition, make alignment sheets 11 with ferromagnetism sheet material, in the matrix of focusing aligner strong magnet 6 is set, rely on the suction of magnet 6, promptly can move the focusing aligner artificially, the aligner that can prevent from again to focus moves on alignment sheets voluntarily.
