Abstract
A camera system has a chassis carrying one or more cameras. Each camera has support member mounted to the chassis and an imaging chip mounted to the support member. An optical system for imaging onto the imaging chip may also be mounted to the chassis. The chassis and support members may have coefficients of thermal expansion that are substantially matched. In some embodiments the support members are located between the imaging chips and one or more circuit boards to which the imaging chips are electrically connected. In some embodiments the imaging chips are located over apertures or other channels through the chassis and light is incident on the imaging chips by way of the channels. The relative locations of the imaging chips can be maintained constant to preserve calibration for stereo imaging.
