| 摘 要： | 根据几何光学和光的标量衍射理论,对双光楔的折射特性进行了数学分析.研究发现,以相反旋向相同转速旋转的双光楔对光的折射作用等效于一个折射角随2个光楔转角变化的单光楔.在此基础上,对通过双光楔的光束在像面上的衍射光场分布作了理论分析,得到了在夫琅禾费衍射下,光束经转动双光楔在像平面上的衍射光斑随时间变化的规律,从而为一维扫描的可控操作提供了理论指导.

| Abstract: | According to the theories of geometric optics and scalar diffraction,the refractive property of light for dual-wedge prism system was analyzed.The study found that the refractive effect of the dual-wedge prism rotating in the same rotation speed and in the opposite direction is equivalent to a single-wedge prism,of which an angle of refraction is changed with the rotary angle between two wedges.On this basis,a theoretical analysis on the diffraction light field of outgoing light through the rotary dual-wedg... |
