Aspherical Lens Design by using Ray Reverse Tracing Method
광선 역추적 방식을 이용한 비구면 렌즈의 설계
- Published : 2003.04.23
Abstract
Aspherical lens design method named ray reverse tracing method is introduced. Differently from the traditional design method, the ray reverse tracing method traces the shape and location of a real object by use of its virtual image. From the result, it was convinced that spherical aberration free aspherical lens could be designed by use of the ray reverse tracing method. Furthermore, it could reduce the degree of dependence of optical characteristics on designer's ability, because deformation terms and optimization can be eliminated, which has been performed in conventional lens design process.
