Abstract: Systems and methods of capturing imagery are provided. In particular, an imaging platform can be configured to capture imagery using a dual-axis steering mirror and one or more image capture devices. The line of sight angle of the imaging platform can be controlled by controlling the motion of the steering mirror in accordance with a motion profile. In example embodiments, the motion profile can correspond to a sawtooth wave. The imaging platform can further include one or more position sensors used to determine a position and/or orientation of the imaging platform along a path on which the imaging platform travels. The motion of the steering mirror can then be controlled to rotate about a first axis and a second axis to compensate for line of sight errors based at least in part on the determined position and/or orientation.
