Design Principles of a High-Speed Omni-Scannable Gaze Controller

Abstract

We propose design principles of a high-speed omni-scannable gaze controller that is advantageous over previously proposed omni-scannable controllers in terms of response time. This is achieved by overcoming the narrow scanning range of the high-speed Saccade Mirror, a gaze controller that employs single-axis rotating mirrors, while maintaining its short response time. It is first shown that in order to achieve an omni-scan with single-axis rotating mirrors, the gaze controller must follow certain conditions. We then give design principles, and determine the positions and shapes through an optimization under evaluation functions and constraints. The response time is estimated by the inertia of the mirrors, and is shown to be superior to conventional commercial omni-scannable gaze controllers.
