摘要

Systems that provide an active adjustment of mirrors and specifically of secondary mirrors, and that provide active adjustment of secondary mirrors in six degrees of freedom, and that can carry the additional load during launch.

1. An apparatus for adjusting motion of a strut, the strut being a component in a positioning mechanism, the apparatus comprising:
a linear motion actuator located substantially parallel to the strut; the strut not being constrained to one dimensional motion; a lever arm component operatively attached at one end to a moving portion of the linear motion actuator and operatively attached to a strut mounting component at a location between the one end and another end; and a flexure operatively attached to the lever arm component at an edge of the lever arm component closest to the strut; the flexure being parallel to the strut and extending from the edge of the lever arm component closest to the strut to a base component; the base component located away from another edge of the lever arm component; the base component being operatively attached to a nonmoving portion of the linear motion actuator and extending from the nonmoving portion of the linear motion actuator to at least a location at which the flexure is attached; a pivot point of the lever arm component being located at a position along the flexure; the flexure being located in a main load path of the strut.
