LCP-27 Kev Ntsuas Qhov Hnyav ntawm Diffraction

Kev Piav Qhia Luv:

Lub kaw lus sim no feem ntau muaj ntau qhov chaw, xws li lub teeb pom kev sim, phaj diffraction, lub tshuab sau qhov muaj zog, khoos phis tawj thiab software ua haujlwm. Los ntawm lub khoos phis tawj interface, cov txiaj ntsig ntawm kev sim tuaj yeem siv ua ib qho txuas rau lub platform optical, thiab nws kuj tuaj yeem siv ua kev sim ib leeg. Lub kaw lus muaj lub sensor photoelectric rau kev ntsuas qhov muaj zog ntawm lub teeb thiab lub sensor hloov chaw siab. Lub ntsuas grating tuaj yeem ntsuas qhov hloov chaw, thiab ntsuas qhov faib tawm ntawm qhov muaj zog diffraction kom raug. Lub khoos phis tawj tswj cov ntaub ntawv tau txais thiab ua cov ntaub ntawv, thiab cov txiaj ntsig ntsuas tuaj yeem piv nrog cov qauv theoretical.
