Abstract:
This study utilizes laser cutting technology to design and fabricate a difraction grating with avariable grating constant based on interlaced slit structure, This design allows for structural deformation tocontrol the beam without the elasticity of the material itself,Multiple experiments were conducted on this gratingto verify and demonstrate its application potential and advantages,The study also explores the impact andpatterns of grating design on diflraction elects, The results show that this grating is suitable for intuitivelydemonstrating difraction and applied in educational settings.
Key words:
