【摘要】 定义了立方角锥棱镜的有效反射区 ,证明了立方角锥棱镜底面角部区域 (即非有效反射区 )入射光与出射光不平行 ,并且在入射光垂直棱镜底面入射情况下计算得有效反射区的面积为底面的三分之二。更多还原

【Abstract】 The effective reflection area of a cubic corner reflector is defined , it is testified for the cubic corner reflector that the ray reflect from this prism is not parallel with the ray incident on the corner of undersurface of this prism , the effective reflection area is calculated in the case of the ray incident on the undersurface of this prism vertically , the acreage of the effective reflection area is two thirds as that of the undersurface of this prism .更多还原
