Description
The present invention is a kind of colour holographic recording medium of photopolymerization imaging system, and the color hologram that can be widely used in white light reconstruction shows aspects such as chromatic information storage.
For many years, one of target of pursuing of holography is to obtain colored picture reproducing.Wherein, the reflection hologram of white light reconstruction is subjected to people's appreciation most.Yet, up to the present, do not develop suitable recording medium, so the color hologram of white light reconstruction is to adopt two kinds of recording medium composite methods to make.Promptly use Agfa 8E75HD silver halide holographic plate and dichromated gelatin holographic plate, make red, green, as to reach blue look image respectively, then they are superimposed together, finally form the color image that white light is penetrated again, this technical sophistication, and the diffraction efficiency of image is lower.
By literature search, netrual colour holographic recording medium still in the relevant patent of the U.S. and Japan though the recording medium of photopolymerization system is arranged, is formed part differently with the present invention, does not have both following characteristic:
Title of the present invention is BGH-2(Beijing university of technology holographic recording medium 2 types again).(647,633nm), green glow (514.5nm) and blue streak (488nm) all have light sensitivity preferably to this medium for ruddiness.
BGH-2 type holographic recording medium of the present invention possesses following characteristic:
Resolution＞4000 lines right/millimeter
2. diffraction efficiency＞75%(is respectively with red, green, blue streak record)
Luminous sensitivity＜80 millijoules/centimetre
2(blue, green glow)
4. feel panchromatic spectral range (see Fig. 1, T% is the percentage of transmitance among the figure)
5. signal to noise ratio (S/N ratio) height,
6. storage life＞6 month,
7. cost is low,
8. nontoxic, pollution-free.
The object of the present invention is to provide a kind of cost low, make simple, and the high colour holographic recording medium of diffraction efficiency.
The present invention can use the white laser of argon-Kr laser emission to write down the bright color hologram image of a width of cloth on a BGH-2; Also can use monochromatic laser (red, green, orchid) to carry out record.
The present invention adds film forming agent (1) by photosensitizer and sheet base (2) is formed, and sees shown in Figure 2.1 is photosensitizer and film forming agent among the figure, the 2nd, and the sheet base.
Photosensitizer is a vinyl monomer, spectral sensitizer, light trigger and auxiliary material are formed, film forming agent is a gelatin, polyvinyl alcohol (PVA), gum arabic, methylcellulose and various can be on the sheet base hydrophilic substance of film forming.The sheet base is substrate glass or flexible material.
Sensitizing dye visual sense light wavelength used in the present invention and deciding sees following table for details

When making photosensitizer, the ratio of red, green, blue three kinds of light intensity of launching according to laser instrument adds the sensitizing dye of two kinds or three kinds proper proportions.
The main manufacture craft of BGH-2 is, after being made into the aqueous solution of photosensitizer, with the gelatin dry plate of making by oneself or buying, in photosensitive liquid, soak sensitization 3-10 minute (15-25 ℃), by taking out the good dry plate of sensitization in the solution, 15-25 ℃ of airing 2 hours, the holographic version that performs, if do not use immediately, under the condition of relative humidity＜40%, 8-12 ℃ of lucifuge stores.Need when using relative humidity as the condition of 80-90% under humidification handled 10 minutes.
The colour reflection hologram that utilizes BGH-2 to make white light reconstruction is seen following embodiment.
