Abstract
Systems and methods described herein are directed to high speed remote imaging systems, such as Light Detection and Ranging (LIDAR) systems. Example embodiments describe systems that are configured to mitigate a walk-off effect that may limit a speed of operation of the imaging system. The walk-off effect may be characterized by a failure to steer returning signals to a designated input facet of the imaging system due to continuous rotation of mirrors associated with the steering mechanisms. The walk-off effect may be mitigating by configuring more than one input waveguide to receiving returning signals associated with an output signal. The input waveguides may be spaced apart and configured to sequentially receive the input signals. In some embodiments, walk-off mitigation may extend a range of operation of the imaging systems.
