Claim 16:
17. The displacement measurement system of claim 1, further comprising:
one or more additional composite subsystems, each additional composite subsystem comprising:
an additional OLA, wherein the additional OLA is configured to:
scan the bump lines and pit lines in the RDMCC to generate a plurality of corresponding electronic signals and the first group of RF signals and
scan the APRCC to generate the plurality of corresponding RF signals, wherein the CCSOU is configured to process the plurality of corresponding RF signals to obtain absolute position reference information;
an additional signal processing unit; and
an additional power driver configured to:
receive control signals from the additional signal processing unit
provide power to an additional 2-D coil actuator in the additional OLA to focus or reposition the laser, and
scan an ADMCC to obtain the absolute position information.
