Description
Technical field
The present invention relates to teaching one-piece field, more particularly to a kind of holography that can be widely applied to teaching field
Intelligent tutoring all-in-one.
Background technology
With the development of science and technology, intelligent tutoring teaching aid is able to extensive use, enriches the content of courses and form, improves
Quality of instruction, holographic technique are referred to teaching field, are substantially carried out article solid show also with intelligent streamlining.
At present, on the one hand, the picture used of imparting knowledge to students is mostly laid out flat, lacks third dimension, it is more preferable to can do nothing to help student
Understand content, be unfavorable for the formation of thinking in images and three-dimensional thinking, teacher in order to be preferably shown to student,
Need to spend more time on graphic plotting and explanation；On the other hand, holographic teaching displaying can not realize a variety of intelligent tutorings
The compatible interaction of function, be difficult to meet during field research it is multi-functional be switched fast, it is right and because more teaching equipments separate
Instructional space causes necessarily to waste.
The content of the invention
It is an object of the invention to mentioned by a kind of holographic intelligent teaching one-piece to solve background section above
The problem of.
To achieve the above object, the present invention uses following technical scheme：
A kind of holographic teaching one-piece, including a player, a displaying cabinet, a hologram display device, an intelligence religion
System.
The player is placed on the object-putting layer of the displaying cabinet upper strata, hologram will be preset in the intelligent tutoring system
As being projected to by the player on hologram display device, the 3 D stereo displaying of resources material is completed.
The cabinet includes framework, two object-putting layers, four Universal pulleys, swivel bearing, touch operation screen, the framework
Sturdy and durable using stainless steel, the object-putting layer includes upper strata object-putting layer, middle level object-putting layer, lower floor's object-putting layer, in described
Stratification nitride layer places hologram display device, and lower floor's object-putting layer is connected by the swivel bearing with middle level object-putting layer, the universal cunning
Wheel can flexibly be put according to teaching scene, can be turned hologram display device direction by the swivel bearing, be completed hologram display
The conversion of device and intelligent tutoring system, can flexibly it be put according to teaching scene by the Universal pulley.
The touch operation screen is embedded in framework side, can be taken off individually operated, can freely be selected by the touch operation screen
The default teaching resource of broadcasting is selected, each functional module of changeable intelligent tutoring system is put down by the touch operation, it is black that electronics is broadcast in choosing
Plate shows content.
The hologram display device includes four sides holographic film plexiglas cone, four fixing devices, and the fixing device is
Four resin fixing devices positioned at the side of rectangle middle level object-putting layer four, ensure that holographic film glass centrum is accurately fixed on position,
Ensure to be not in inconsistent phenomenon in transfer process, to ensure holographic imaging quality.
The player provides high-resolution holography material, and the holographic material carries out sampling of data by the server, obtained
Each discrete point centrifugal pump on to thing, further according to all parameters are set, calculated using matlab language, it is complete by being calculated
It is the optical field distribution in plane, light field is encoded, draws the transmitance of hologram, form hologram on this basis.This
One process can be described as, and the light wave that object is sent is assumed plane light wave, and wavelength is definite value, phase 0, is chosen on object
Certain point, its amplitude size are the pixel value, pass through A on diffraction propagation to holography（X, y）, select reference light wave B（X, y）With y
Direction forms conjugation, and A points are added with B points and draw interference complex amplitude U（X, y）, to interfering complex amplitude U（X, y）Modulus square root,
Holographic interference pattern is drawn, the basis as hologram reconstruction.
The reproducing processes of hologram be can be described as, and phase is being carried out to the sampling interval of thing function and frequency spectrum function through oversampling
After should setting, it is assumed that it is MxN that sample points are taken on holographic interference pattern reproduction plane X1, Y1 directions, and sample interval is Δ X1x Δs
Y1, hologram plane X, it is MxN that Y-direction, which takes sample points, and sample interval is Δ Xx Δ Y, reappears formula using convolution method：
U（R Δs X1, s Δ Y1）=F^-1 { F [I (M Δs X, N Δ Y) * r（M Δs X, N Δ Y）] * F [g (M Δs X, N Δ Y)]
（Wherein, I (M Δs X, N Δ Y), r（M Δs X, N Δ Y）Respectively input, export variation function, F is Fourier transform）
By computer by digital hologram I（M, N）Simulate and reproduce light r（M, N）, Fourier transform is done to hologram, simultaneously
Identical conversion is done to point spread function, the hologram being in after conversion in frequency domain is multiplied with transmission function, then with Fourier
Inverse transformation, spatial domain is again converted to from frequency domain, further ensures and reproduce holographic phase Pixel Dimensions and hologram size guarantor
Hold unanimously, form the hologram reconstruction of high quality.
Reproducing holographic phase Pixel Dimensions and hologram size has a uniformity, the hologram of the player plays with
Reproduce it is holographic related, according to light the holographic film plexiglas cone medium refractive index, the player plays it is complete
Breath figure will be influenceed that angle change occurs by medium refraction index.Digital hologram is calculated through server simulation, is passed through again
After medium refraction, to meet displaying demand of imparting knowledge to students, the holographic images, the player of application and the holography that are reproduced by the hologram display device
Displays have following data characteristics.
| Liquid crystal screen dimensions | Shield viewing area（mm） | Display device one side show region（mm） | Ranges of indices of refraction（n） |
| 50 cun | 1016*762 | 635* 476.25 | 1.6 |
| 60 cun | 1219*914 | 761.88*571.25 | 1.6 |
| 70 cun | 1463*1097 | 914.38*685.63 | 1.6 |
The intelligent tutoring system includes server, intelligent interactive electronic blackboard, and subordinate server includes control module, data
Storage device.The control module completes various integrated functionality switchings, is realized by the intelligent interactive electronic blackboard specific
Teaching is applied, including the various functions such as full frame touch-control, video playback, phonetic search, preset storage in the data storage device
