Abstract
The utility model discloses a rainbow hologram and producing device which relates to the laser hologram technology. A bunch laser generates a space spot light source array through a fly lens, recording holographic gratings of different forms on a same holographic dry plate, only needing single exposure, and a holographic rainbow sheet with various patterns can be formed. The device can be widely used for the setting, etc. of close-up photograph, trademarks, advertisements, decorations, lamps, toys, dance halls, theaters and commodity windows.
Description
The utility model relates to the laser hologram photography technology.
Existing 85104065 holo-rainbow sheet patents, adopt and rotate the dry plate method for multiple exposures with multiple, the multiple holographic grating that intersects at a certain angle of multiexposure, multiple exposure record on same holographic dry plate, make the holo-rainbow sheet, this holo-rainbow sheet and manufacturing installation thereof exist some shortcomings: (1) is for obtaining uniform beam, need that light beam is divided into two bundles and carry out spatial filtering respectively, light path is complicated.(2) rotating operation that in the darkroom, carries out certain angle difficulty relatively.(3) for obtaining each grating identical diffraction efficiency is arranged, control very difficult the strictness of holographic exposure amount or time shutter.(4) because can only expose a sinusoidal grating at every turn, it is very bothersome, time-consuming that multiple grating will carry out multiexposure, multiple exposure.(5) because the sensitization dynamic range of photographic emulsion is limited, thereby the crossed grating number that enables to write down is restricted, and makes the design pattern kind of holo-rainbow sheet limited.
The utility model aims to provide a kind of holo-rainbow sheet and manufacturing installation thereof.
The technical scheme that the utility model adopted is: produce a spatial point array of source with a plane wave laser beam by a fly lens, the holographic grating that the spherical wave that sends from these pointolites with the holographic dry plate record interferes with each other, only need carry out single exposure just can obtain a holo-rainbow sheet.By blocking the diverse location on the fly lens and the lenslet of quantity, just can on same holographic dry plate, write down the holographic grating of various ways, thereby make various holo-rainbow sheets with the stopple plate that is in the light.The pattern of this holo-rainbow sheet can be symmetrical distribution or asymmetric distribution, by an incandescent light source irradiation holo-rainbow sheet, just can see that design pattern is various in style, make the satisfied picture scape of people.
The advantage that the utility model had:
1. employing beam of laser, expansion bundle filtering collimation is adjusted more convenient, has saved element, has simplified light path system.
2. owing to only need single exposure, do not need multiexposure, multiple exposure and rotate the holographic recording dry plate, processing ease, writing speed are fast.
3. write down complicated holographic grating with single exposure, be not subjected to the restriction of emulsion sensitization dynamic range, can increase raster count.
The design pattern that reveals again of holo-rainbow sheet various in style, have and be symmetrically distributed and the pattern of asymmetric distribution, be simply to rotate the dry plate method for multiple exposures with multiple to be beyond one's reach.
The utility model embodiment is as follows:
Accompanying drawing 1 is a theory diagram of the present utility model.
Laser instrument (1) sends a branch of light, enter expansion bundle filtering optical system (3) afterwards through colimated light system (2), make laser beam carry out spatial filtering and expand Shu Biancheng uniform in-plane ripple, the stopple plate (4) that is in the light places fly lens (5) the place ahead (also can be fixed on the fly lens (5)), blocks the lenslet that fly lens (5) is gone up diverse location and varying number as required.After the pointolite array of multi beam directional light in being focused into same focal plane by fly lens (5), becoming the multi beam spherical wave exhales, holographic dry plate (6) places the holographic grating of the part place record various ways that overlaps mutually of these spherical waves, only need carry out single exposure, after holographic dry plate (6) being carried out the chemical treatment and bleaching of routine, just can obtain recording the holo-rainbow sheet of various ways.
Claims (3)
1, the holo-rainbow sheet that adopts laser beam to expose on holographic dry plate and make is characterized in that adopting beam of laser to pass through a fly lens and produces a spatial point array of source, and only single exposure is made on holographic dry plate.
2, the manufacturing installation of holo-rainbow sheet, include laser instrument (1), colimated light system (2), filtering optical system (3), it is characterized in that LASER Light Source adopts the beam of laser from laser instrument (1), and, on holographic dry plate, write down complicated holographic grating with single exposure by a fly lens (5) generation spatial point array of source.
3, manufacturing installation as claimed in claim 2, the stopple plate (4) that it is characterized in that being in the light places the place ahead of fly lens (5), also can be fixed on the fly lens (5).
