Prism design for image orientation changes by the screw triangle method.
We apply the screw triangle method (STM), which was conventionally used in the field of mechanism design, to design a prism to produce a specified image orientation change (IOC). Compared to existing methods [Tsai and Lin, Appl. Opt.45, 3951 (2006); Appl. Opt.46, 3087 (2007)], the proposed method is both simpler and more efficient, since its derivations are essentially vector-based calculations. The validity of the proposed approach is demonstrated via an illustrative example.
