ABSTRACT:
Optical delay line system that includes a retro-reflection mirror which is displaced along a circular path while being maintained in angular alignment with launch and return sources of light subject the components of the system to minimum levels of unbalanced linear acceleration. A retroreflector is pivotally mounted on a rotating element such that the optical axis of the retroreflector's motion is mobile such that its angle or position changes relative to a fixed observer. There is no linear stopping and starting of the retroreflector and all acceleration of the retroreflector is rotational acceleration with small angles so the required forces in the optical delay line are greatly reduced. Both large displacement and high repetition rates are achieved. The system can be configured so that optical fibers serve as launch and return optics. Alternatively, free space beam paths deliver light to the optical delay and return the reflected light from the retroreflector.
