Simulation and experimental research based on abbe imaging and spatial filtering

Based on the teaching model of Abbe imaging and spatial filtering, this research, in combination with specific experimental practice, conducts visual simulation by using the MATLAB numerical calculation method. Through the integration of theory, simulation, and experiment, this research proposes a flexible optical path design method, which is beneficial for drawing inferences from others. The proposed method is convenient for students to deeply understand the principles of Abbe imaging and spatial filtering, further assisting theoretical teaching activities.
