Abstract
A housing for a control device includes an enclosed cavity configured to secure an optical detection system, including a light source and a sensor, and a face of the enclosed cavity configured to include a window to allow light from the light source to scatter light off of a surface and configured to allow reception of the scattered light on the sensor. In this configuration the housing is structured to prevent exposure of the optical detection system to external elements such as the surface. Also disclosed is a homodyning system for use with a coherent light source optical pointing device.
