Embodiment

Below in conjunction with Figure of description, patent of the present invention is described in further detail.

Embodiment one

As shown in Figure 1, idle light path is LG to the schematic diagram of a kind of Quantum Correlation formation method tangled based on Angle Position of the present invention _{+ l, 0}pattern, signal light path is LG _{-l, 0}pattern, wherein LG _{+ l, 0}and LG _{-l, 0}pattern be a branch of Gauss's pump light through Ι type degenerate non-linear phase matcher, produced by parametric down conversion process.Gray-scale values different according to object in signal light path selects the fan-shaped phase place of different angle seam θ, and is loaded in signal light path.Such as, suppose that the gray shade scale of the object to be imaged is M, namely the gray scale value of the object to be imaged is 0,1 ... M-2, M-1.The angle of angle seam θ is selected to be changed to 0 to π this interval (because the coincidence counting corresponding to 0 to π interval is a monotonic quantity), M the angle seam θ value from 0 to π will be obtained, namely angle seam θ can be set to 0 respectively, π/(M-1), 2 π/(M-1) ..., (M-2) π/(M-1), and π, M gray-scale value of imaging object and M angle seam θ one_to_one corresponding.Then signal light path and idle light path are carried out coincidence measurement and obtain coincidence counting, finally obtain the half-tone information of the object to be imaged according to funtcional relationship dull between coincidence counting and angle seam angle, thus recover the object to be imaged in reference path.

In theory, when under Gauss's pump light is by Spontaneous Parametric, conversion obtains signal photon and idle photon entanglement pair, two-photon state can be expressed as:

$|\mathrm{\ψ}\⟩=\underset{n=-\∞}{\overset{n=+\∞}{\mathrm{\Σ}}}{c}_n|-n{\⟩}_s|n{\⟩}_i,---\left(1\right)$

Wherein, | n> represents the orbit angular momentum state (LG pattern) of l=n pattern, | c _n| ²to represent under Spontaneous Parametric that in transfer process, pump photon is converted into ± probability of n photon.Because conversion under Spontaneous Parametric has symmetry, have:

c _n＝c _-n， (2)

In order to provide coincidence counting and the corresponding relation of different angle seam information, derive the expression-form of the coincidence counting when signal light path loads different angle seam phase place below.

Suppose that the basic state of signal light path and idle light path is respectively |-l> and |+l>, in the angle seam phase place as shown in Figure 2 that signal light path loads, wherein white portion phase value is 0, grey parts phase value is π, the angle seam angular dimension of grey parts is θ, then the phase place corresponding to angle seam can be expressed as:

$M\left(\mathrm{\&phi;}\right)=\left\{\begin{array}{cc}\mathrm{\&pi;}& 0\&le;\mathrm{\&phi;}\&le;\mathrm{\&theta;},0\&le;r\&le;r_0\\ 0& \mathrm{\&theta;}<\mathrm{\&phi;}\&le;2\mathrm{\&pi;},0\&le;r\&le;r_0\end{array}\right.,---\left(3\right)$

Wherein θ is the angle representing angle seam, its transformation range 0≤θ≤2 π; r ₀it is the radial radius size of angle seam.Because the originate mode of signal light path input is the OAM state of-l, its mathematical form is |-l>=Aexp (-il φ), wherein Α is LG pattern radial distribution, has nothing to do with the value of l.Therefore, the OAM state after signal light path loads angle seam θ | Ψ _s> is:

|Ψ _s>＝Ae ^-ilφe ^iM(φ)(4)

Because different l value LG pattern is mutually orthogonal, therefore loading the signal state after angle seam θ deployable is various l value LG patterns, namely

$|{\mathrm{\&psi;}}_s\&rang;=\underset{l^{\&prime;}=-\&infin;}{\overset{l^{\&prime;}=+\&infin;}{\mathrm{\&Sigma;}}}{A}_{l^{\&prime;}}|l^{\&prime;}\&rang;---\left(5\right)$

Wherein A _{l '}for:

$A_{l^{\&prime;}}=\frac{1}{2\mathrm{\&pi;}}\mathrm{d\&phi;}{e}^{-i{l}^{\&prime;}\mathrm{\&phi;}}A{e}^{-\mathrm{il\&phi;}}{e}^{\mathrm{iM}\left(\mathrm{\&phi;}\right)}---\left(6\right)$

Further for above formula abbreviation can be obtained:

$A_{l^{\&prime;}}=A\left\{\begin{array}{cc}\frac{-\mathrm{\&theta;}}{\mathrm{\&pi;}}{e}^{-i(\mathrm{\&theta;}/2)(l^{\&prime;}+l)}\sin c[\left(\frac{\mathrm{\&theta;}}{2}(l^{\&prime;}+l)\right),& l^{\&prime;}\&NotEqual;-l\\ 1-\frac{\mathrm{\&theta;}}{\mathrm{\&pi;}},& l^{\&prime;}=-l\end{array}\right.,---\left(7\right)$

Due to idle light path OAM state | Ψ _i> is the OAM state of+l, can be expressed as

|Ψ _i>＝|+l>， (8)

According to coincidence counting formula, the coincidence counting C (Ψ of signal light path and idle light path can be obtained _s, Ψ _i) be:

C(Ψ _s,Ψ _i)＝|<Ψ _s|<Ψ _i|Ψ>| ²， (9)

Wherein:

$\begin{array}{c}\&lang;{\mathrm{\&psi;}}_s|\&lang;{\mathrm{\&psi;}}_i||\mathrm{\&psi;}\&rang;=[\underset{l^{\&prime;}=-\&infin;}{\overset{l^{\&prime;}=+\&infin;}{\mathrm{\&Sigma;}}}{A}_{l^{\&prime;}}\&lang;l^{\&prime;}\left|\right]\&lang;+l\left|\underset{n=-\&infin;}{\overset{n=+\&infin;}{\mathrm{\&Sigma;}}}{c}_n\right|n\&rang;|-n\&rang;\\ =[\underset{l^{\&prime;}=-\&infin;}{\overset{l^{\&prime;}=+\&infin;}{\mathrm{\&Sigma;}}}{A}_{l^{\&prime;}}\&lang;l^{\&prime;}|\left]c_l\right|-l\&rang;\end{array}$

$\begin{array}{c}=A[1-\frac{\mathrm{\&theta;}}{\mathrm{\&pi;}}]\&lang;-l\left|c_l\right|-l\&rang;\\ =c_{l}A(1-\frac{\mathrm{\&theta;}}{\mathrm{\&pi;}})\end{array},---\left(10\right)$

Can be obtained by two formulas above:

$C({\mathrm{\&psi;}}_s,{\mathrm{\&psi;}}_i)={|\&lang;{\mathrm{\&psi;}}_s|\&lang;{\mathrm{\&psi;}}_i\left|\right|\mathrm{\&psi;}\&rang;|}^2=c_l^2{A}^2{(1-\frac{\mathrm{\&theta;}}{\mathrm{\&pi;}})}^2,---\left(11\right)$

Wherein, c _lall constant with A, therefore:

$C({\mathrm{\&psi;}}_s,{\mathrm{\&psi;}}_i)\&Proportional;{(1-\frac{\mathrm{\&theta;}}{\mathrm{\&pi;}})}^2,---\left(12\right)$

Fig. 3 is | Ψ _s> and | Ψ _ithe degree of conformity graph of a relation of >, shows C (Ψ _s, Ψ _i) and the relation of angle theta.As can be seen from the figure along with angle theta change to π from 0 time, C (Ψ _s, Ψ _i) be reduced to minimum value from maximal value, along with angle theta change to 2 π from π time, C (Ψ _s, Ψ _i) be increased to maximal value from minimum value.

Can find by Fig. 3, when the primary input state of signal light path and idle light path is |-l> and | during+l>, be the monotonous descending function of loading fan-shaped phase place angle theta in 0 to π interval coincidence counting value.If signal light path is | the OAM light of-l> pattern, idle light path input | the OAM light of+l> pattern.When loading the fan-shaped phase place of different angle theta in signal light path, will different coincidence counting values be obtained in idle light path, and between coincidence counting value and angle seam angle θ, there is dull funtcional relationship.Because different angle seam correspond to the different gray scales of the object to be imaged, therefore can realize the differentiation of the different gray-scale value of imaging object in idle light path, obtain image objects.Specific implementation step of the present invention is as follows:

Step one: a branch of Gauss's pump light, through Ι type degenerate non-linear phase matcher, is produced by parametric down conversion process and tangles light a pair, be respectively flashlight and idle light.The photon produced is to being expressed as wherein s and i represents signal light path and idle light path respectively, | l> represents that exponent number is the eigenstate of the orbital angular momentum of l.| c _l| ²it is the probability that two photon exponent numbers are respectively l and-l pattern.

Step 2: set up the Quantum Correlation imaging scheme of tangling based on Angle Position as shown in Figure 1, idle light path input LG _{+ l, 0}pattern, signal light path input LG _{-l, 0}pattern.In signal light path, first gray-scale values different for object is encoded into different angle seam angle θ, and being loaded in signal light path with the form of fan-shaped phase place, the present invention selects 0 to this interval of π (0 to π interval corresponding coincidence counting and angle seam angle θ are a monotonic quantity).If the gray shade scale of imaging object is M, i.e. value 0,1, ..., M-2, M-1, then corresponding angle seam angle θ is 0, π/(M-1), 2 π/(M-1) ..., (M-2) π/(M-1) and π, evenly be divided into M part by 0 to π interval, M angle seam θ value is corresponding with M gray-scale value.

Step 3: signal light path and idle light path are carried out coincidence measurement, obtains coincidence counting.From Such analysis, there is one-to-one relationship in the angle theta of the fan-shaped phase place that signal light path loads and coincidence counting value, c _lbe all constant with A, by coincidence counting value, the corresponding fan-shaped phase theta size loaded can be obtained.

Step 4: the relation between the angle seam size obtained by step 2 and gray-scale value, obtains the gray-scale value of each pixel, by computing machine Recovery image.
