摘要
传统物理光学测试实验平台利用Virtual Lab软件用户界面对物理光学实验结果进行呈现,结构设计灵活性差、准确度低,为此设计了一种新的物理光学测试实验智能平台,该平台由虚拟仪器库、算法库、事实库和推理机等构成,光源由光源室及稳流电源构成,保障光源工作波长和稳定性;采用Maya2000pro型光栅光谱仪作为探测器转换光学信号与电信号,实现光源强度波动的测试。平台采用向前演绎推理方法设计推理机工作流程,推理运算事实库当前内容;利用衍射光栅物理模型仿真光栅衍射过程。实验结果表明,所设计平台能够有效进行干涉实验和衍射实验,模拟光波长时最大误差为0. 13%,说明所设计平台具有较高的准确性。
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.
