Abstract

A scanning system includes a scanning structure configured to rotate about at least one first scanning axis; a driver configured to drive the scanning structure about the at least one first scanning axis and detect a position of the scanning structure with respect to the at least one first scanning axis during movement of the scanning structure; a segmented pixel sensor including a plurality of sub-pixel elements arranged in a pixel area; and a controller configured to selectively activate and deactivate the plurality of sub-pixel elements into at least one active cluster and at least one deactivated cluster to form at least one active pixel from the at least one active cluster, receive first position information from the driver indicating the detected position of the scanning structure, and dynamically change a clustering of activated sub-pixel elements and a clustering of deactivated sub-pixel elements based on the first position information.
