THE OVERALL VISION OF THIS RESEARCH IS THE APPLICATION OF HIGHLY ACTIVE LIGHTWEIGHT PRIMARY MIRRORS RECENTLY DEVELOPED IN OUR GROUP TO CORONAGRAPH SYSTEMS ON LARGE SEGMENTED SPACE TELESCOPES IN ORDER TO MITIGATE SYSTEM MISALIGNMENTS AND EDGE DIFFRACTION FROM THE SEGMENTED APERTURE AND PRIMARY MIRROR FIGURE ERRORS INDUCED BY TELESCOPE JITTER AND VIBRATION. SEGMENTED PRIMARY PUPILS POSE UNIQUE COMPENSATION PROBLEMS THAT CANNOT BE FULLY ADDRESSED BY STATE OF THE ART CONTINUOUS DEFORMABLE MIRRORS ON THE OPTICAL PATH. THE FUNDAMENTAL PROBLEM IS THAT ACTUATION OF THE DEFORMABLE MIRROR NEAR THE EDGE OF ONE PUPIL SEGMENT WILL NECESSARILY RUN OVER TO AN ADJACENT SEGMENT DUE TO THE FINITE WIDTH OF THE ACTUATOR INFLUENCE FUNCTIONS. ACTIVE PRIMARY SEGMENTS THAT ARE ENTIRELY INDEPENDENT FROM EACH OTHER CAN ELIMINATE THIS PHENOMENON. MANAGING DIFFRACTION IN THIS WAY AT THE ENTRANCE PUPIL MAY ALSO PERMIT THE ELIMINATION OR REDUCTION IN COMPLEXITY OF THE OFTEN DIFFICULT TO MANUFACTURE SHAPED PUPIL APODIZERS. AN ADDITIONAL LIMITATION OF CURRENT TELESCOPES IS IMPACT ON IMAGE QUALITY FROM VIBRATION AND JITTER OF THE MIRROR SEGMENTS WHICH IS CURRENTLY ADDRESSED BY SPECIALIZED SPACECRAFT SPECIFIC STRUCTURAL DESIGNS AS WELL AS THE OPTICAL COMPLEXITY OF ADDITIONAL DEFORMABLE AND FAST STEERING MIRRORS. AN ALTERNATIVE APPROACH IS PROPOSED BASED ON FAST HIGHLY DISTRIBUTED SHAPE SENSING IN COMBINATION WITH THE ACTIVE PRIMARY. THIS RESEARCH WILL DEVELOP ANALYTICAL AND SOFTWARE TOOLS TO MINIMIZE THE CONTRIBUTIONS OF DIFFRACTION AND JITTER VIBRATION TO THE OVERALL SYSTEM ERRORS. HARDWARE IMPLEMENTATIONS OF SELECTED SOLUTIONS WILL BE BUILT AND TESTED IN AN EXISTING TESTBED.
