Abstract:
1. An optical scanner, comprising: a mirror mounted for rotation around at least two axes of rotation, the at least two axes of rotation having a first axis of rotation and a second axis of rotation; a first actuator that rotates the mirror around the first axis of rotation; a first driver that drives the first actuator; a first angular position sensor that senses an angular position of the mirror around the first axis of rotation; a second actuator that rotates the mirror around the second axis of rotation; a second driver that drives the second actuator; a second angular position sensor that senses an angular position of the mirror around the second axis of rotation; a controller coupled to the first and second drivers to drive the respective first and second actuators to rotate the mirror into respective angles around the first and second axes of rotation, respectively; and a memory storing a set of scan patterns, wherein the set of scan patterns includes a first scan pattern and a second scan pattern that is different from the first scan pattern; wherein the controller is configured to access one of the scan patterns from the memory, and control a positioning of the mirror based at least in part on the one of the scan patterns accessed from the memory.
