RANGING CAMERAS USING A COMMON SUBSTRATE

摘要

A stereo camera system useful in, for example, range finding applications. The system is designed for simple manufacture and long term stability. It includes a thermally stable substrate onto which are mounted multiple imagers. The relative positions of the imagers and corresponding optical elements are maintained in precise alignment.

主权项

1. A stereo ranging system, comprising:
a common substrate having a flat surface and including a stiffening material having substantially the same coefficient of thermal expansion as other materials in the common substrate; and at least two semiconductor imagers secured to the flat surface of the common substrate and maintained at predefined locations relative to the flat surface.
