The operation of the optical D-disjunctor of fuzzy sets is as follows. From the output of AI 1 optical stream with an intensity of 4 × n srvc. units arrives at the input of the optical Y-splitter 2, from the first output of which an optical stream with an intensity of 2 × n srvc. units arrives at the input of the first optical n-output splitter 3. From the second output of the optical Y-splitter 2 an optical stream with an intensity of 2 × n srvc. units arrives at the input of the second optical n-output splitter 5.

At all outputs 3 ₁ , 3 ₂ , ..., 3 _{n of the} first optical n-output splitter 3, optical flows with an intensity of 2 conv. units These n flows with an intensity of 2 srvc. units each, they arrive at the corresponding inputs of LOT 4, forming an optical stream with an intensity proportional to 2 × μ _A (x _i ) at each of its ith outputs, i.e. proportional to the value of the membership function µ _A (x) for a particular ith value of the argument x _i (i = 1, 2, ... n). Further, these optical flows arrive at the first inputs of the corresponding BV 7 ₁ , 7 ₂ , ..., 7 _n .

At the same time, at all outputs 5 ₁ , 5 ₂ , ..., 5 _{n of the} second optical n-output splitter 11, optical flows with an intensity of 2 conv. units These n flows - with an intensity of 2 srvc. units each, they arrive at the corresponding inputs of LOT 6, forming an optical stream with an intensity proportional to 2 × μ _B (x _i ) at each of its ith outputs, i.e. proportional to the value of the membership function µ _B (x) for a particular i-th value of the argument x _i (i = 1, 2, ... n). Further, these optical flows arrive at the second inputs of the corresponding BV 7 ₁ , 7 ₂ , ..., 7n.

The work of the i-th BV 7 _i is as follows.

From the output of the AI 13 to the input of the optical three-output splitter 14 receives an optical stream with an intensity of 3 srvc. units From the first output 14 ₁ optical three-output splitter 14 optical flow with an intensity of 1 srvc. units arrives at the second input of the first optical Y-combiner 9. From the second output 14 _{3 of the three} -output optical splitter 14, an optical stream with an intensity of 1 conv. units arrives at the second input of the second optical Y-combiner 16. From the third output 14 ₃ optical _three -output splitter 14 optical flow with an intensity of 1 srvc. units arrives at the input of the second optical waveguide 22 _{2 of the} third pair of OCB 22 ₁ , 22 ₂ .

Let µ _A (x _i ) = 0, and 0≤µ _B (x _i ) ≤1. Then, at the first input of the i-th BV 7 _{i there is} no optical flow, and at the second input of the i-th BV 7 _i there is an optical stream with an intensity of 2 × μ _B (x _i ) conv. units Since nothing arrives at the input of the first optical Y-coupler 8, accordingly, there is no optical flow at the information input of the first EDI 12, and nothing arrives at the first input of the first optical Y-combiner 9 either. At the output of the first optical Y-combiner 9 there is an optical stream with an intensity of 1 srvc. units This optical stream enters the input of the first optical waveguide 10 _{1 of the} first pair of OCB 10 ₁ , 10 ₂ and, without switching to the second optical waveguide 10 _{2 of the} first pair of OCB 10 ₁ , 10 ₂ , enters the input of the first FP 11. At the output of the first FP 11 the control signal of the second EDI 19 is formed.

Simultaneously with the first output of the second optical Y-splitter 15, an optical stream with an intensity of μ _B (x _i ) conv. units arrives at the information input of the second EDI 19, and from the second output an optical stream with an intensity of µ _B (x _i ) conv. units arrives at the first input of the second optical Y-combiner 16. Since the specified control signal is supplied to the second EDI 19, an optical stream with intensity µ _B (x _i ) conv. units from the output of the EDI 19 is directed to the second input of the third optical Y-combiner 20. From the output of the third optical Y-combiner 20, an optical stream with an intensity of μ _B (x _i ) is fed to the input of the first optical waveguide 22 _{1 of the} third couple of the OCB 22 ₁ , 22 ₂ . In this case, an optical stream with an intensity of µ _B (x _i ) +1 srvc. units from the output of the second optical Y-combiner 16 gets to the input of the first optical waveguide 17 _{1 of the} second pair of OCB 17 ₁ , 17 ₂ . When µ _B (x _i ) ≥0.05 srvc. units, and therefore, μ _B (x _i ) +1) ≥1.05 srvc. units this optical stream is switched into the second optical waveguide 17 _{2 of the} second pair of the OCB 17 ₁ , 17 ₂ and is absorbed. Thus, at the input of the second FP 18, there will be no optical flow, and, therefore, at the output of the FP 18 no electrical control signal is generated by the first EDI 12, and at the second input of the AND-NOT logic element 21 there is no electric signal. Since the electrical signal is present at the output of the first FP 11, the electric control signal PE 23 is absent at the output of the AND-NOT 21 logic element, into which the third pair of WWS 22 ₁ , 22 ₂ is integrated. Therefore, the distance between the optical waveguides of the third pair of OCB 22 ₁ , 22 _{2 is} large and switching the optical flow with an intensity of 1 srvc. units from the second optical waveguide 22 ₂ in the first 22 ₁ does not occur. Therefore, from the output of the first optical waveguide 22 _{1 of the} third pair of OCB 22 ₁ , 22 _{2, an} optical stream with intensity µ _B (х _i ) is supplied to the output of БВ7 _i

Thus, when μ _A (x _i ) = 0, the output of the i-th BV 7 _i will contain an optical stream with an intensity of μ _B (x _i ) conv. units

Let µ _B (x _i ) = 0, and 0≤µ _A (x _i ) ≤1. Then at the first input of the i-th BV 7 _i there is an optical stream with an intensity of 2 × μ _A (x _i ), and at the second input of the i-th BV 7 _{i there} is no optical stream. Since nothing arrives at the input of the second optical Y-coupler 15, accordingly, there is no optical flow at the information input of the second EDI 19, and nothing arrives at the first input of the second optical Y-combiner 16 either. At the output of the second optical Y-combiner 16 there is an optical stream with an intensity of 1 srvc. units This optical flux enters the input of the first optical waveguide 17 _{1 of the} second pair of OCB 17 ₁ , 17 ₂ and, without switching to the second optical waveguide 17 _{2 of the} second pair of OCB 17 ₁ , 17 ₂ , enters the input of the second phase 18. At the output of the second phase 18 an electrical control signal is generated by the first EDI 12.

Simultaneously, from the first output of the first optical Y-splitter 8, an optical stream with an intensity of μ _A (x _i ) conv. units arrives at the information input of the first EDI 12, and from the second output an optical stream with intensity µ _A (x _i ) conv. units arrives at the first input of the first optical Y-combiner 9. Since the specified control signal is supplied to the first EDI 12, an optical stream with intensity µ _A (x _i ) conv. units from the output of the EDI 12 is directed to the first input of the third optical Y-combiner 20. From the output of the third optical Y-combiner 20, an optical stream with an intensity of μ _A (x _i ) is fed to the input of the first optical waveguide 22 _{1 of the} third OSB 22 ₁ , 22 ₂ . In this case, an optical stream with an intensity of μ _A (x _i ) +1 srvc. units from the output of the first optical Y-combiner 9 gets to the input of the first optical waveguide 10 _{1 of the} first pair of OCB 10 ₁ , 10 ₂ . For µ _A (x _i ) ≥0.05 conv. units, and therefore (µ _A (х _i ) +1) ≥1.05 conv. units this optical flux is switched to the second optical waveguide 10 _{2 of the} first pair of OCB 10 ₁ , 10 ₂ and is absorbed. Thus, at the input of the first FP 11 there will be no optical flow, and therefore, at the output of the FP 11 no electrical control signal of the second EDI 19 is generated, and there is no electric signal at the first input of the AND-NOT logic element 21. Since an electric signal is present at the output of the second FP 18, an electric control signal PE 23 is absent at the output of the NAND gate 21, into which a third pair of WWS 22 ₁ , 22 ₂ is integrated. Therefore, the distance between the optical waveguides of the third pair of OCB 22 ₁ , 22 _{2 is} large and switching the optical flow with an intensity of 1 conv. units from the second optical waveguide 22 ₂ in the first 22 ₁ does not occur. Consequently, from the output of the first optical waveguide 22 _{1 of the} third pair of OCB 22 ₁ , 22 _{2, an} optical stream with an intensity µ _A (x _i ) arrives at the output of BV7 _i

Thus, when μ _B (x _i ) = 0, the output of the i-th BV 7 _i will contain an optical stream with an intensity μ _A (x _i ) conv. units

Let 0≤µ _A (x _i ) ≤1 and 0≤µ _B (x _i ) ≤1. Then at the first input of the i-th BV 7 _i there is an optical stream with an intensity of 2 × µ _A (x _i ) conv. units This optical stream enters the input of the first optical Y-splitter 8, from the first output of which an optical stream with intensity µ _A (x _i ) conv. units arrives at the information input of the first EDI 12, and from the second output an optical stream with intensity µ _A (x _i ) conv. units arrives at the input of the first optical Y-combiner 9. Therefore, from the output of the first optical Y-combiner 9, an optical stream with an intensity (μ _A (x _i ) +1) conv. units will be fed to the input of the first optical waveguide 10 _{1 of the} first pair of OCB 10 ₁ , 10 ₂ . For µ _A (x _i ) ≥0.05 srvc. units, and therefore, for (μ _A (x _i ) +1) ≥1.05 srvc. units this optical flux is switched to the second optical waveguide 10 _{2 of the} first pair of OCB 10 ₁ , 10 ₂ and is absorbed. Thus, there will be no optical flow at the input of the first FP 11, and therefore, no electrical control signal of the second EDI 19 is generated at the output of the FP 11.

At the same time, at the second input of the i-th BV 7 _i there is an optical stream with an intensity of 2 × μ _B (x _i ) conv. units This optical stream enters the input of the second optical Y-splitter 15, from the first output of which an optical stream with an intensity of µB (x _i ) conv. units arrives at the information input of the second EDI 19, and from the second output an optical stream with an intensity of µ _B (x _i ) conv. units arrives at the input of the second optical Y-combiner 16. Therefore, from the output of the second optical Y-combiner 16, an optical stream with an intensity (μ _B (x _i ) +1) conv. units will be fed to the input of the first optical waveguide 17 _{1 of the} second pair of OCB 17 ₁ , 17 ₂ . When µ _B (x _i ) ≥0.05 srvc. units, and therefore (µ _B (х _i ) +1) ≥1.05 srvc. units this optical stream is switched into the second optical waveguide 17 _{2 of the} second pair of the OCB 17 ₁ , 17 ₂ and is absorbed. Thus, at the input of the second FP 18, there will be no optical flow, and therefore, at the output of the FP 18, an electrical control signal of the first EDI 12 is not generated.

Since at the control input of the first EDI 12 there is no predetermined control signal, an optical stream with intensity µ _A (x _i ) conv. units from the output of the EDI 12 is not sent to the first input of the third optical Y-combiner 20 and is absorbed. Since the control input of the second EDI 19 also does not have a predetermined control signal, the optical flux with intensity µ _B (x _i ) conv. units from the output of the EDI 19 is not sent to the second input of the third optical Y-combiner 20 and is absorbed. Therefore, the output of the third optical Y-combiner 20 will be no optical flow.

In the absence of electrical signals at the output of the first FP 11 and the second FP 19 at the output of the AND-NOT logic element 21, a control signal PE 23 arises, ensuring the approach of the waveguides of the third pair of OCB 22 ₁ , 22 ₂ so that an optical connection appears between them. Therefore, an optical stream with an intensity of 1 srvc. units from the third output 14 _{3 of the} optical _three -output splitter 14 through the second optical waveguide 22 _{2 of the} third couple of the OCB 22 ₁ , 22 ₂ switches to the first optical waveguide 22 _{1 of the} third pair of the OCB 22 ₁ , 22 ₂ and then goes to the output of the BV 7 _i .

Thus, for 0≤µ _A (x _i ) ≤1 and 0≤µ _B (x _i ) ≤1, an optical stream with an intensity of 1 srvc will be present at the output of the i-th BV 7 _i units

When μ _A (x _i ) = 0 and μ _B (x _i ) = 0, there are no optical flows at the first and second inputs of the i-th BV 7 _i . Therefore, at the output of the i-th BV 7 _i there will also be no optical flow (optical signals do not pass from the outputs of the EDI 11, 9 to the corresponding inputs of the third optical Y-combiner 20, while the output of the AND-NOT logic element 21 will be absent PE control signal 23).

From the above it follows that at the output of the i-th BV 7 _i the following optical flows are formed (i = 1, 2, ... n):

- intensity flux µ _A (x _i ) conv. units when µ _B (x _i ) = 0;

- intensity flux µ _B (x _i ) conv. units for µ _A (x _i ) = 0;

- 1 conv. units in all other cases.

Thus, at the output of each i-th BV 7 _i , an optical flow is formed, the intensity of which is proportional to the value of the membership function µ _D (x _i ) for a particular value of x _i (i = 1, 2, ... n).

Therefore, at the outputs of all BV 7 ₁ , 7 ₂ , ... 7 _n - at the output of the device, a flat optical stream is formed with an intensity along the Ox axis proportional to the membership function µ _D (x) corresponding to the result of the D-disjunction operation of two fuzzy sets defined by the equality (one).

The speed of the optical D-disjunctor of fuzzy sets is determined by the dynamic characteristics of the piezoelectric element, photodetectors, electro-optical deflectors and the logical AND-NOT element. The cutoff frequency of the piezoelectric elements is 10 ⁸ Hz. Photodetectors, made in the traditional version based on photodiodes, have a cutoff frequency of 10 ⁹ Hz, and electro-optical deflectors - 10 ¹⁰ Hz. The delay time of a logic element made in an integrated version based on the TTLS logic is 10 ^-9 s. For existing continuously logical information processing systems, such a speed ensures their operation in almost real time.
