The present disclosure relates to systems and methods operable to provide point cloud information about an environment based on reconfigurable spatial light emission patterns and reconfigurable light detector arrangements that correspond to the light emission patterns. Additionally, a LIDAR device with a plurality of light emitters and photodetectors may be operated in a first mode of operation or a second mode of operation. The first mode of operation could be a normal mode of operation. The second mode of operation could be a failsafe mode of operation that is used when a fault condition is detected.
