Detailed Description

The quantum thin film photoelectric sensor 9 is a photoelectric sensor provided with a quantum thin film layer, so that the quantum thin film is applied to the field of quantum random numbers, and the rate of the random numbers can be greatly improved.
The data processing module (data processing unit in fig. 6) comprises a microcontroller mounted in the housing, which is located on the main circuit board 3 in fig. 2. The light source 5 and the quantum thin film photoelectric sensor 9 are connected with the microcontroller. Noise analysis and random number extraction can be achieved by the microcontroller.
The display module comprises a dynamic simulation lamp 11 and a touch display screen 12; the dynamic simulation lamp 11 and the touch display screen 12 are installed on the shell 1, the touch display screen 12 and the dynamic simulation lamp 11 are connected with the microcontroller, and the brightness of the point light source 5 in the darkroom is dynamically followed through the dynamic simulation lamp 11.
In an embodiment, the light source 5 is an RGB three-color LED point light source 5, which can realize single-color light and multi-color light, and each light intensity is adjustable, and the relationship between the random number and the light intensity and color can be observed. As shown in fig. 3, the LED driving board 4 is fixed on the first fixing frame 6, and the LED driving board 4 is provided with an RGB three-color LED point light source 5. As shown in fig. 8, the EN pin, the SCL pin, and the SDA pin of the LED driving board 4 are connected to the microcontroller, and the D1 pin, the D2 pin, and the D3 pin of the LED driving board 4 are respectively connected to an LED point light source 5.
As shown in fig. 4, the lens module 8 includes a lens and a frame support 7, and the lens is fixed to the frame support 7. Preferably, the lens module 8 is a lenticular lens module 8. The convex lens plane outer region is provided with the shading part, converts point light source 5 into parallel light, can let point light source 5 parallel emission to quantum thin film photoelectric sensor 9 on to ensure the homogeneity and the independence that light passes through lens.
In one embodiment, the dynamic analog light 11 is an LED light, and the LED light forms an LED matrix. The LED lamps are composed of 0402 surface mounted lamps, and each group of LED lamps is provided with a lampshade with transparent top ends and isolated at the periphery, so that the display is ensured not to interfere with each other and the dynamic effect is ensured. As shown in fig. 7, the driving chip of the LED matrix adopts IS31FL3743A, IS31FL3743A chip IS connected to the microcontroller, CS1, CS2, …, CS17, CS18 pins of IS31FL3743A chip are respectively connected to the corresponding LED lamp sets, SW1, SW2, …, SW10, SW11 pins of IS31FL3743A chip are connected to switches SW1, SW2, …, SW10, SW11, when the pins CS1, CS2, …, CS … are low, the pins SW …, SW … are high, the lamps of the LED matrix are turned on, and any one of the output levels of the pins SW …, CS …, and CS … IS controlled to turn on or off. The dynamic generation process of the quantum random number adopts an RGB three-color LED matrix, and students can edit the favorite dynamic process.
By utilizing the randomness of the arrival time of the photons, the RGB three-color LED point light source 5 is placed in the device, and the colors of red, green and blue or any color which is supposed to be verified through experiments can be adjusted independently, so that the light intensity can be adjusted, and the photon saturation interval can be verified. The point light source 5 is emitted in parallel to the quantum thin film photosensor 9. By using the quantum thin film technology, light can be directly projected on the quantum thin film, and then the CMOS silicon device at the lower part of the quantum thin film is responsible for converting image signals received by the quantum thin film into digital signals. The quantum thin film photoelectric sensor 9 realizes photon collection, converts the photons into DVP digital signals and sends the DVP digital signals to the microcontroller for pretreatment. A threshold interval of an entropy value is preset in a microcontroller, when the entropy value is small, the number of photons absorbed by a pixel is small, and the influence of noise is very obvious; when the entropy value is large, the number of photons absorbed by the pixel is close to the saturation value, and the obtained data is inaccurate. And comparing the average value of each pixel with a preset threshold interval, if the average value of a certain pixel is within the threshold interval, sending the pixel to an extractor for extraction, and otherwise, discarding the pixel to omit the condition of large and small entropy values. After receiving the DVP data, the microcontroller analyzes the noise and outputs the display result to the touch screen 12 for display. The cool and dynamic LED matrix dynamically simulates the quantum random number generation process. The display result is visually seen through the touch display screen 12 and operation control can be performed on the touch display screen 12.
In an embodiment, the optical simulation darkroom 2 employs a blackbody light shield, which can effectively shield external light interference.
In one embodiment, the touch screen display 12 is a capacitive touch screen display 12, which facilitates viewing and interaction.
As shown in fig. 5, the quantum thin film photosensor 9 is fixed to the second fixing frame 10.
As shown in fig. 1, the system further includes a USB interface 13, the USB interface 13 is connected to the microcontroller, and the microcontroller outputs data to the backend for use through the USB interface 13. The external USB interface 13 can conveniently communicate with external equipment, and data can be conveniently extracted.
In one embodiment, the microcontroller further comprises a memory, such as an SDRAM (synchronous dynamic random access memory), an EEPROM (electrically erasable and programmable read only memory), an NAND FLASH memory, an SPI FLASH memory, etc., which is connected to the microcontroller. The memory may store client character codes and other client information elements for character output reduction operations.
The invention applies the quantum film to the field of quantum random number, and is different from a CMOS image sensor in that the quantum film is a material based on nanotechnology, and the quantum dot film which is more sensitive to light is arranged above a silicon layer, so that optical signals can be converted into digital signals, and the sensor can capture all light without barriers. Therefore, the quantum thin-film photosensor 9 is thinner and lighter and has stronger performance than a conventional CMOS sensor. Because the light absorbing material used in CMOS sensors is silicon, which is originally used to conduct electricity rather than absorb light, the ability to absorb light is not optimal; the CMOS sensor process can only load 4000 electrons, which appear white when the 4000 electrons are fully charged, but each pixel of the quantum thin film can load 12000 electrons, i.e., the quantum thin film can greatly increase the number of photons obtained, thereby greatly increasing the rate of random numbers. The invention has low price.
