REDUCING SIZE OF LIDAR SYSTEM CONTROL ASSEMBLIES

A LIDAR system has one or more light splitters and multiple light combiners. The LIDAR system also has multiple optical pathways through which light signals travel. The optical pathways include delay pathways that each extends from one of the one or more splitters to one of the light combiners. The optical pathways include expedited pathways that each extends from one of the splitters to one of the light combiners. Each of the light combiners has one of the delay pathways and one of the expedited pathways extending to the light combiner. The delay pathways and the expedited pathways are configured such that the delay pathway to each light combiner is longer than the expedited pathway to the same light combiner. Each of the delay pathways has a common portion and a separated portion. The common portion of each delay pathway is shared by the other delay pathways. In contrast, the separated portion of a delay pathways is not shared with the other delay pathways.
