Generate hologram and the specific algorithm and the principle that reproduce left images
The specific algorithm for generating hologram and reproduction left images of explanation the application and principle below, and with
The method for generating hologram and reproduction left images of lower record is relevant be applied to above any one embodiment
The operation generating hologram and reproducing left images.
Algorithm and principle
Specifically, algorithm and principle one are to calculate the wavefront complex amplitude letter of three-dimensional object by Fresnel Diffraction Integral
Number, generates hologram using the method for wavefront information superposition, specific as follows：
Step 1) calculate complex amplitude before the Object light wave of the object light of three-dimensional object reflection
It is possible, firstly, to calculating diffraction distance by following (formula 1) is complex amplitude function before the Object light wave of d：
Wherein, d is diffraction distance, (x0,y0) on starting material popin face with coordinate x0And y0Corresponding, O (x0,y0) be
Starting material popin surface information function, U (x, y) is complex amplitude function before diffraction distance is for the Object light wave of d, and λ is the ripple of object light
Long, j is imaginary unit, and k is wave number, x0、y0For original object plane coordinate, x, y are the wavefront function through diffraction apart from d diffraction
Plane coordinates.
Then, (formula 1) is integrated processing, the item unrelated with integration variable is mentioned before the sign of integration, obtains (formula
2)：
As can be seen that (formula 2) is right from above-mentioned (formula 2)It has been a Fourier to become
Change, then, transformation results are multiplied by a quadratic phase factor, that is, againWith regard to permissible
Obtain through complex amplitude before Object light wave after d diffraction for the diffraction.In order to calculate above formula using fast fourier transform FFT, can
Fourier transform is represented with F, object plane sampling width is L0, hits is N × N, and sampling interval is Δ x0=Δ y0=L0/ N,
Then, above-mentioned (formula 2) is rewritten as (formula 3), that is,：
In (formula 3), Δ x=Δ y is corresponding Space domain sampling spacing after discrete Fourier transform (DFT), now, according to Fu
Vertical leaf transformation and the relation of discrete Fourier transform (DFT), can obtain (formula 4)：Wherein, in (formula 4), L is
Through diffraction apart from d diffraction pattern sample range.(formula 4) is entered line translation and obtains (formula 5)：
On the other hand, according to nyquist sampling theorem, meet (formula 6) when only having：Retouched
During the condition stated, discrete calculation result could approximately meet the diffractional field of nyquist sampling theorem.Now, object plane and diffraction
The sampling width of field plane is equal, and from (formula 5), now object plane and diffractional field width are equal, that is,
Therefore, result above shows, if keeping the sampling interval of object plane and observation area constant, discrete Fourier becomes
Change diffraction pattern on plane of vision for the result of calculation and sample range L and be not only wavelength X and the function of sampling number N, and can be with
Diffraction increases apart from the increase of d.When diffraction is apart from very little, if sampling number N keeps constant, result of calculation can only correspond to
The diffraction image in neighbouring optical axis very little region on plane of vision.
Step 2) holographic production is carried out to three-dimensional object A according to principle of holography, that is, simulate by reference to interference of light thing
Light wavefront complex amplitude U (x, y), obtains objective holographic figure IH(x, y), IH(x, y) contains the three-dimensional information (amplification of virtual objects
And phase information).In the embodiment of the present application, objective holographic figure can be calculated by following (formula 7),Wherein, R (x, y) table
Show reference light, U (x, y) represents complex amplitude function (that is, above-mentioned wavefront information), R before the Object light wave of diffraction*(x, y) represents
Reference light is conjugated, and U* (x, y) represents complex amplitude function conjugation before Object light wave.
Step 3) according to the viewpoint demand of virtual reality system, generate and left view point and the corresponding left image of right viewpoint and the right side
Image.Simulate different reference angles of light (i.e. the angle of the normal of incident reference light and hologram), hologram is entered
Row reproduces.When reference light is R (x, y), Fresnel hologram is IHWhen (x, y), the optical field distribution of reproduction is：
Formula 8) in, F is function Fourier transform symbol, and d is diffraction distance, and λ is wavelength, and j is imaginary unit, and k is wave number,
(x, y) is the hologram plane coordinates through diffraction apart from the wavefront function generation of d diffraction, and (x ', y ') is to shine through reference light
Penetrate the reproduction image plane coordinates of hologram generation, (Δ x ', Δ y ') corresponds to Space domain sampling spacing.Below, shown in refer to the attached drawing 10
To step 3) make and illustrating.
First, the visual field scope of human eye is 30 degree to 100 degree, during the reconstruction of hologram, is selected according to human eye visual field scope
Meet the left view point of system requirements and right viewpoint, and reproduce with left view point and the corresponding left view point of right viewpoint according to reference to light settings
Reference light and right viewpoint reproduce reference light.For example, reproduce reference light incident angle when setting reproduction as α, then reproduce reference light
Expression formula is changed into R (x, y) exp (jkxsin α).According to formula (8), secondary reproduction reference light expression formula is substituted in formula (8)：
By formula (9) as can be seen that incident angle has affected only the phase information of reconstruction results.Therefore, two are selected
Different incident angle α, that is, select the reproduction reference light of two out of phase information, thus in the viewpoint of corresponding left and right, then
Now generate the left images that system needs.
