Abstract

The purpose of this thesis is to describe the design process, goals, and analysis of the interior vision camera for a driver monitoring system. The design includes minimizing the overall footprint of the system by utilizing smaller more precise optics, as well as higher quantum efficiency (QE) image sensor technologies and packaging. As a result of this research, prototype cameras are constructed, and performance was analyzed. The analysis shows that Modulation Transfer Function (MTF) performance is stable at extreme hot and cold temperatures, while the cost is mitigated by using all plastic lens elements. New high QE image sensors are a potential improvement to this design. The mechanical part of the design has resulted in the filing of three different patents. The first patent was the athermalization spacer itself for automotive applications. The second patent was the way the lens barrel interacts with the athermalization piece. The third patent was the way the imager assembly accommodates the same Bill Of Material (BOM) components and different customer requirement angles.
