Abstract:
Certain embodiments described herein relate to a scanning controller configured produce a horizontal (H) and vertical (V) scanning control signal that is used to control a bi-axial scanning mirror of a scanning laser projector device, a system including such a scanning controller, and a method for generating such an H and V scanning control signal. In an embodiment, the H and V scanning control signal includes H scanning frequency content that is used to control a H scanning frequency of the bi-axial scanning mirror, and V scanning frequency content that is used to control a V scanning frequency of the bi-axial scanning mirror. To avoid cross talk, the scanning controller is configured to produce the H and V scanning control signal such that the H scanning frequency content has a null at DC, and the V scanning frequency content has a null at the H scanning frequency.
