A LIDAR can encounter a remotely located mirror as it moves through a local environment (e.g. a convex roadside mirror). The remote mirror can occupy a small portion of the LIDAR field of view but offer a wealth of reflection data regarding a larger indirect field of view (e.g. around a corner). In one embodiment a LIDAR can learn the location of the remote mirror and then can dynamically increase the density of laser ranging measurements in an associated mirror region of the field of view. The LIDAR can track the mirror region as it moves in the local environment with an increased density of outgoing laser pulses and thereby interrogate the remote mirror for reflection data from a wide indirect field of view.
