Background technology
Utilize the specific light wave that principle of interference sends object to record with the form of interference fringe, the full detail of object light wavefront is all stored in recording medium, the interference fringe pattern recording is called as hologram.When irradiating hologram with playback light, by diffraction principle, reappear original object light wavefront, thereby human eye can be observed the 3-D view identical with the original.Holographic technique is a kind of unconventional imaging technique, not yet universal in actual life, common people do not know this technology, holographic technique imaging is a kind of stereo-picture simultaneously, there is stronger visual impact, therefore the hologram image of a kind of cheapness and safety reproduces toy, will there are great market prospects.
Formation of hologram process is: monochromatic collimation laser is after beam splitter, through beam expanding lens, disperse respectively, as coherent reference light and object light, after object light is irradiated on target object, through diffuse reflection and reference light, on holographic recording medium, form interference fringe, then through development, cleaning and fixing, form the hologram egative film of the stereo image information with the original.
During by hologram reconstruction original stereo-picture, the angle of divergence of the angle of divergence that needs playback light reference light when for recorded hologram.For this reason, in the playback light light path of the holographic three-D image transcriber of prior art, all adopt beam expanding lens to make monochromatic collimated beam become diverging light.In order to dwindle the volume of transcriber, require the angle of divergence of diverging light larger, the beam expanding lens focal length of employing must short (being generally less than 20mm).The cost of beam expanding lens accounts for 30% to 40% of whole reproduction light path, and simultaneously above-mentioned beam expanding lens requires less rigging error, thereby makes whole light channel structure become complicated.
Holographic three-D image transcriber as a toy purposes, first will guarantee the security of this device, can not hurt observer's eyes, and the structure of this device should be tried one's best simply simultaneously, and cost is as far as possible cheap.
Summary of the invention
The purpose of this utility model is to overcome existing hologram image transcriber structure relative complex, and cost is high, is unsuitable for making the deficiency of toy, provides a kind of safe, simple in structure, with low cost hologram image to reproduce toy.
The technical solution of the utility model is to provide a kind of hologram image and reproduces toy, and spot light collimation laser device, frosted glass and cone are fixedly assemblied on urceolus, have a slot on urceolus, and hologram inserts wherein; Urceolus is two-section shape, cooperatively interacts and is inserted in the distance between rear telescopic adjustment frosted glass and hologram; Described spot light collimation laser device sends the collimation collimated laser beam that spot diameter is 2mm～5mm, frosted glass surface is vertical with collimation collimated laser beam, distance between frosted glass and hologram is 120mm～250mm, and the angle between frosted glass and hologram is 0 °～10 °.
The power of spot light collimation laser device described in the utility model is 3mw～5mw.Described frosted glass is single or double ground glass, and thickness is 1mm～3mm.：
Compared with prior art, the advantage that the hologram image that the utility model provides reproduces toy is: utilize the diffuse scattering characteristic of frosted glass to make the laser beam of concentration of energy become the light of dispersing to all directions, energy disperses, thereby avoids the injury of laser beam to human eye, safer; Meanwhile, its structure is very simple, can significantly reduce production costs.
