Active/adaptive actuator design of an adaptive optic mirror

An active/adaptive actuator for an adaptive optic mirror comprising:

• A. A case mounted next to said adaptive optic mirror;
• B. a holding plate with a preset plurality of openings rigidly mounted within said case;
• C. a calibration mounting plate rigidly placed in said case such that said holding plate is between said calibration mounting plate and said adaptive optic mirror, said calibration mounting plate having a plurality of openings matching in number those in said holding plate and axially aligned with said openings in said holding plate;
• D. a plurality of support collars, one each mounted in each of said openings in said holding plate;
• E. a plurality of differential threads, one each threaded into each of said support collars;
• F. a plurality of actuator holders one each threaded into each of said differential threads;
• G. a plurality of actuators, one each mounted to each of said actuator holders and operably connected to said adaptive optic mirror;
• H. a first adjustment handle which fits through said openings in said calibration mounting plate such that it operably connects to said support collars, one at a time, so as to turn said support collars;
• and
• I. a second adjustment handle which is inserted through said first adjustment handle so it operably connects to said differential thread while said first adjustment handle is operable connected to the support collar threaded to said differential thread so as to turn said differential thread independently of turns to said support collar.
