Abstract
- The article discusses the techniques of using ray tracing to guide the construction of freeform mirrors which can be applied to a variety of problems. The U.S. Defense Advanced Research Projects Agency has designed pinhole camera which allows the light to enter through single point to project three-dimensional image plane. Based on mathematical analysis, the images produced in a camera is distorted if a curved mirror intervenes between object and hole.
