Magnification of spatial position of a light beam caused by multi-reflection between prisms

Abstract

In a light beam incident to rectangular prisms facing each other and making multi-reflection between the prisms, the spatial position of the beam is magnified until double of the number of multi-reflection times. The effect is also shown in a pair of large and small corner cube prisms. This pair can save effectively the space of multi-reflection and change the spatial position of the reflected beam to both X and Y axes at the same time. These are clarified and summarized with analytical drawings.
