摘要
首先简要回顾了获得平行出射光的反射曲面的求解过程,给出了一种实用解的形式,提出抛物面反射的簇投射机制,并详细分析了实际辐射经抛物面反射后的出射光的偏移特性及偏移量分析、计算方法.接下来给出了应用中给定距离上的投射照度的一种理论表示方法和抛物面参数的一种确定方法.最后分析了抛物面在实际应用中的局限性,指出有源光学系统的优化设计统筹源设计在内的重要性.结束部分给出了一种潜在的实际应用方向.
On reviewing of the procedure of the solution of the question that how a point source can get parallel reflection from curved surface, a solution is offered with practical value. The mechanism of cluster projection is brought forth along with the analysis of the drift of reflected radiation. As to application, it is presented that how to calculate the luminous of surface on the distance fixed and how to pin down the parameter of the paraboloid. At the end, it is emphasized that the optimum design of a optical system with source inside had better seal the source design in.
