Tracking motion using an interference pattern |
摘要 |
A system, method, and device for tracking motion across a surface by creating an interference pattern by reflecting light from the surface. There is produced, as a result of sensor moving across the surface, at least one signal pattern corresponding to a detection of a dimension of the interference pattern. This detected dimension is associated with an assumed dimensional value to determine a distance traveled by the sensor.
