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 定義了立方角錐棱鏡的有效反射區，證明了立方角錐棱鏡底面角部區域(即非有效反射區)入射光與出射光不平行，并且在入射光垂直棱鏡底面入射情況下計算得有效反射區的面積為底面的三分之二。 |
