[0002] Traditional bifocal optical system design and optimization mainly rely on experimental methods and empirical formulas, which is not only time-consuming and labor-intensive, but also difficult to fully and accurately predict the performance of the system under actual working conditions. With the rapid development of computer technology and simulation technology, it has become possible to design and optimize bifocal optical systems through simulation methods. Simulation technology can simulate the working process of bifocal optical systems in a virtual environment and predict system performance, thereby greatly shortening the design and optimization cycle and reducing development costs.

[0003] However, the existing laser beam simulation technology still has some problems in practical applications. On the one hand, the accuracy and reliability of the simulation model need to be improved. The complexity of the dual-focus optical system requires that the simulation model must be able to accurately reflect the actual working state of the system, including the characteristics of the laser light source, the interaction of optical components, and the influence of environmental factors. On the other hand, the controllability and automation of the simulation process are insufficient. In traditional simulation methods, it is often necessary to manually set simulation parameters, monitor the simulation process, and analyze the simulation results, which not only reduces the simulation efficiency, but also easily introduces human errors.

[0039] We have designed a specific embodiment that uses a complete laser beam simulation system based on a dual-focus optical system and processes and analyzes simulation tasks according to the method steps of the present invention.

[0040] Step 1: System parameter collection and model construction System parameter acquisition: The system parameter acquisition device was used to measure the laser light source of the dual-focus optical system in detail, and key parameters such as laser wavelength (such as 532nm), power (such as 1W), and beam quality factor (such as M²=1.2) were obtained. At the same time, the system parameters of the dual-focus optical system were also measured, including two focal lengths (such as f1=100mm, f2=50mm), lens curvature, material refractive index (such as n=1.5), etc.

[0041] Model construction: In the simulation module, a bifocal optical system simulation model was established based on the measured bifocal optical system parameters, which accurately reflects the optical characteristics of the bifocal optical system. According to the laser light source parameters, a laser light source simulation model was established, which can simulate the output characteristics of the laser light source. The bifocal optical system simulation model was combined with the laser light source simulation model to form a laser beam simulation model based on the bifocal optical system, which provides a basis for subsequent simulation tasks.

[0042] Step 2: System simulation error calculation Simulation test: According to the preset test simulation parameters (such as beam incident angle, spot size, etc.), simulation was performed based on the laser beam simulation model to obtain standard test result data. At the same time, the same parameters were tested using the actual dual-focus optical system to obtain the corresponding simulation test result data.

[0043] Error calculation: Compare the standard test result data and the simulation test result data, and find that there is a certain difference between the two. Calculate the difference between the two as the system simulation error and record it in the cloud data server for subsequent use.

[0044] Step 3: Simulation task processing and container generation Task submission: The user submits a simulation task through the simulation request client and sets the simulation parameters (such as beam incident angle, spot size, simulation time, etc.).

[0045] Container generation: After receiving the simulation request task, the simulation module dynamically generates a simulation container for executing the simulation task. The simulation request client transmits the specific parameters of the simulation request task to the simulation container.

[0046] Model connection: The laser beam simulation model is connected to the simulation container and is ready for simulation. The simulation control module is also connected to the simulation container to allow real-time control and monitoring during the simulation process.

[0047] Step 4: Simulation execution and comparison value calculation Simulation execution: Based on the constructed laser beam simulation model, simulation was performed according to the simulation parameters in the simulation request task, and simulation result data of the corresponding simulation task was obtained.

[0048] Comparison value calculation: Add the simulation result data and the system simulation error to obtain the simulation comparison value of the corresponding simulation task. The simulation comparison value is used for subsequent data consistency verification and performance change characteristic analysis.

[0049] Step 5: Independent simulation of the simulation control module Independent simulation: The simulation control module independently simulates according to the simulation parameters in the simulation request task and obtains another set of simulation result data corresponding to the simulation task. This set of simulation result data is used to compare and verify the simulation results of the laser beam simulation module.

[0050] Step 6: Data consistency check Data comparison: By comparing the simulation control values ​​obtained by the laser beam simulation model and the simulation result data obtained by the simulation control module, it is found that the difference between the two is very small.

[0051] Consistency check: Calculate the data difference between the two, and further calculate the ratio of the data difference to the simulation result data. If the ratio is much smaller than the set threshold (such as 0.05), the data is considered consistent and proceed to the next step. If the ratio is greater than the set threshold, a simulation device failure message is issued to prompt the user to check and repair.

[0052] Step 7: Simulation task completion and performance change characteristics analysis Mission accomplished: The simulation mission was successfully completed and accurate simulation result data was obtained.

[0053] Performance analysis: According to the difference between the simulation control value and the simulation result data of the corresponding simulation task, the performance change characteristics of the simulation system are analyzed. The data difference of each simulation task is calculated, and the difference change rate is further calculated. The difference change rate is defined as: (data difference of the current simulation task - data difference of the previous simulation task) / data difference of the previous simulation task. If the difference change rate is within the set change threshold range (such as ±0.1), the simulation system is considered stable; otherwise, the simulation system is considered unstable and needs further inspection and adjustment.
