An optical design with a pyramid prism array is employed to simultaneously capture four images. The apex angle design of an upper and lower prism array is to form the upper and the lower images of the object. The design of the left and right prism array is to develop the left and right images. In the prism array, the unwanted image can be eliminated by blacken process in the plane gap between each prism. The optical design was based on the pyramid prism array and a single-lens to make the system light, portable and low-cost.
Key words: optical design, pyramid prism array, stereoscopic camera
