Abstract:

THE PROBLEM OF INSTABILITY IN MEMBRANE MIRRORS USED IN WAVEFRONT CORRECTORS AND THEIR STABILIZATION BY ACTIVE CONTROL IS PROPOSED. SUCH SYSTEMS DISPLAY AN INSTABILITY IN THE TRANSVERSE VIBRATION, WHICH LEADS TO UNACCEPTABLE ERRORS IN OPTICS AND AN INABILITY TO INCREASE THE NUMBER OF MIRROR ACTUATORS TO LEVELS COMPATIBLE WITH FUTURE APPLICATIONS. RECOGNITION OF THE INSTABILITY MECHANISM AND ITS STABILIZATION ARE DIFFICULT DUE TO THE MATHEMATICAL COMPLEXITY. THE POWERFUL GMS TECHNIQUE DEVELOPED BY THE PRINCIPAL INVESTIGATOR WILL BE EMPLOYED TO SOLVE THE PROBLEM. SIMILAR SYSTEMS HAVE BEEN SUCCESSFULLY ANALYZED BY THIS METHOD. PHASE I GOALS INCLUDE (1) GMS ANALYSIS OF MEMBRANE DYNAMICS AND, (2) IDENTIFICATION OF PARAMETERS INFLUENCING INSTABILITIES, AND (3) DEVELOPMENT OF CONTROL LAWS FOR STABILIZATION AND/OR DESIGN CONSTRAINTS.
