Claim 17:
18. The displacement measurement system as in claim 1, further comprising one or more additional composite subsystems, wherein each additional composite subsystem comprises:
one or more optical laser assemblies (OLAs);
one or more signal processing units configured to receive electronic signals from the one or more OLAs; and
one or more additional power drivers; wherein the RDMCC is scanned and a control signal is generated therefrom, producing the first group of RF signals to obtain incremental displacement information, wherein a second composite subsystem comprises:
at least a second optical laser assembly;
at least a second signal processing unit which is configured to receive the electronic signals from the one or more OLAs; and
a device configured to perform fine adjustment of relative offset between the first composite subsystem and one of the other compositive subsystems.
