1. A method for optical metrology comprising:
receiving an external data reading exerted on a transmission structure, wherein the transmission structure comprises one or more surfaces;
measuring distance from one or more sensors to a plurality of optical metric markers;
calculating a plurality of three-dimensional positions of the plurality of optical metric markers based on the external data and the distance from one or more sensors to the plurality of optical metric markers;
characterizing at least one of the one or more surfaces attached to the plurality of optical metric markers;
comparing current surface orientation of the transmission structure to a predefined target orientation;
assessing current transmission for post-estimator error;
revising current estimations based on post-estimator error;
implementing mechanical adjustment of the transmission structure.
