The traditional physical optics testing platform has poor flexibility and accuracy in structure design.A new intelligent platform for physical optics experiment is designed.The platform is composed of virtual instrument library,algorithm library,facts library and inference machine.The light source is composed of light source room and steady current power supply to ensure the working wavelength and stability of the light source.The Maya2000 pro optical grating spectrometer is set as the prober convert the optical signal and electric signal to realize the testing of source intensity fluctuations.The platform uses forward deductive reasoning method to design the workflow of reasoning engine,reasoning and computing the current content of the fact base,and simulates the diffraction process of grating by using the diffraction grating physical model.The experimental results show that the designed platform can effectively carry out interference and diffraction experiments,and the maximum error is 0.13%when simulating the wavelength of light,indicating that the designed platform has high accuracy.
