Description
Technical field
The present invention relates to line holographic projections field, particularly hologram display tutoring system.
Background technology
Line holographic projections technology also claims virtual image technology, is to utilize interference and diffraction principle record and the technology of the recording and reconstruction of the real 3-D view of reconstructed object.Its first step utilizes principle of interference record object light-wave information, and this i.e. shooting process: object line holographic projections shooting process body forms the object beam of diffuse type under laser irradiation; Another part laser is as being mapped on holofilm with reference to light beam, produce with object beam superposition and interfere, the position phase of each point on object light wave and amplitude are converted to the intensity spatially changed, thus utilizes the contrast between interference fringe and interval to be recorded by the full detail of object light wave.The egative film that record interference fringe, after development, the handling procedure such as fixing, just becomes a hologram, or claims hologram.Its second step utilizes diffraction principle reconstructed object light-wave information, this is imaging procedures: the grating that hologram is complicated just as, under coherent laser illumination, the diffraction light wave of the sinusoidal pattern hologram of a linear recording generally can provide two and resemble, and namely originally resembles and conjugate image.The image stereoscopic sensation reproduced is strong, has real visual effect.Every part of hologram all have recorded the optical information of each point on object, therefore its every part can reproduce the whole image of the original in principle, multiple different image can also be recorded on same egative film by multiexposure, multiple exposure, and can show respectively without interfering with each other.
At present, line holographic projections technology is tentatively used in fields such as exhibition, advertisement, teaching, and the major advantage of this technology 3-dimensional image can be suspended to be presented in the air, build also unreal also genuine atmosphere, effect is peculiar, has strong depth feelings, and true and false difficulty is debated.Line holographic projections Technology application can be solved space structure indigestion well in teaching field, three-dimensional view is difficult to understand fully, the motion of very complicated is difficult to the problems such as comprehensive research, so that student is to the understanding of teaching object space structure, deepens the understanding to teaching object.Chinese patent notification number CN204557823U discloses a kind of hologram display tutoring system, comprises and shows mechanism and rotation platform, and described rotation platform can drive shows mechanism's rotary display line holographic projections or showpiece in kind.Also can introduce elevating mechanism and camera mechanism respectively in the bottom of rotation platform and outside in addition, play respectively to regulate and show that mechanism height and shooting hologram or showpiece in kind are to amplify the effect of display.Hologram display tutoring system structure of the present invention is simple, is easy to operation, and cheap, and easy accessibility, can show showpiece in kind or hologram all sidedly, and can be shot with video-corder amplification displaying, has good teaching application prospect.There is following problem in the program: generally, in order to make the better effects if of line holographic projections, when watching the displaying of line holographic projections, other light are shut by capital, but such people are operating the bracing frame of line holographic projections, when making line holographic projections platform be elevated, accurately cannot see the position of hand switch, thus extend the running time.
Summary of the invention
The object of this invention is to provide hologram display tutoring system, making people when operating, the position of hand switch can be seen, thus the platform of exact operations line holographic projections.
The invention provides a kind of base case: hologram display tutoring system, comprise and show mechanism and hoistable platform, the bottom showing mechanism is located at by hoistable platform, show that mechanism comprises support, top platen, imaging cone seat and base plate, connected by support between top platen and base plate, imaging cone seat is positioned at substrate; Hoistable platform comprises lifting support and base, and lifting support upper end is connected with base plate lower surface, and lifting support lower end is connected with base, is provided with the hand switch for regulating lifting support above sidewall of the bottom plate; Also comprise image mechanism, image mechanism comprises camera, connecting link and brace, camera can rotatably be articulated with connecting link top by horizontal rotary, brace one end level is fixed on the lower surface of base plate, the other end is connected with connecting link lower end is vertical, base plate surrounding is provided with LED, infrared ray sensor and controller, and LED, infrared ray sensor and controller are electrically connected.
Principle of work and beneficial effect are: present tutoring system generally adopts projector to release the picture of two dimension, to launch teaching, and the enjoyment during students' response is imparted knowledge to students.Different from prior art, adopt line holographic projections technology, the image of two dimension are become three-dimensional hologram image, make teaching efficiency better.Wherein, adopt and show mechanism, by camera facing to imaging cone seat, in imaging cone seat, be formed centrally 3-D view, allow student can be on the spot in person, increase teaching enjoyment.Meanwhile, lifting support is set, makes imaging bore seat and can carry out height adjustment, so that in teaching process, all students can be watched.In viewing process, to highly regulating, as dark as a stack of black cats around, so arrange induction installation, adopt hand to stop infrared sensor, thus send signal to controller, controller can order LED be opened, and can have light like this at hand switch place, avoids extending the running time, and handled easily, and the effect of line holographic projections can be ensured.
Further prioritization scheme one for base case: be provided with roller below base, can move line holographic projections equipment like this, to be placed into the place that student can see.
Further prioritization scheme two for prioritization scheme one: be arranged with dust cover above top platen, can avoid dust to fall like this and show in mechanism, affect the effect of line holographic projections.
Further prioritization scheme three for base case: imaging cone seat adopts steel to mould glass and makes, firm in structure like this, compared with general plastics, long service life, and hardness is good, the imaging cone seat be converted into is more three-dimensional.
Further prioritization scheme four for base case: lifting support comprises inner and outer tubes, interior pipe is nested in relative sliding inside outer tube, and can carry out height to the exhibiting device of line holographic projections like this and regulate, the student being applicable to different height uses.
