WE PROPOSE AN EFFORT IN WHICH A UNIVERSITY OF ROCHESTER TEAM LEAD BY PROF. JAMES R. FIENUP APPLIES REFINED PHASE RETRIEVAL ALGORITHMS THAT WILL SUPPORT NASA'S IMAGE/BASED WFSC FOR ALIGNMENT OF THE JAMES WEBB SPACE TELESCOPE (JWST)DURING GROUND TESTING DURING COMMISSIONING AFTER LAUNCH AND FOR TELESCOPE MAINTENANCE FOR NON-IDEAL SITUATIONS FOR WHICH THE BASELINE WFS APPROACHES WERE NOT DESIGNED. THIS EFFORT WILL SUBSTANTIALLY REDUCE THE RISK OF FAILURE DURING GROUND TESTING AND ON-ORBIT USE OF THE SYSTEM.
