Abstract: The Phased Array Mirror, Extendible Large Aperture (PAMELA) prototype telescope phase I testing and verification has been completed. The prototype telescope is the first to have a fully adaptive primary mirror which consists of 36 hexagonal injection-molded Pyrex segments that are seven centimeters flat-to-flat. The segments are mounted on three long-throw voice-coil actuators for tip, tilt, and piston motion. The segments' tilts are measured with a Hartmann- Shack wavefront sensor, and the piston errors between adjacent segments are measured via inductive edge-sensors. The 0.5 meter telescope was successfully operated with simultaneously closed tilt and piston control loops for the entire array. Phase I test and verification results are shown for the closed loop operations.!12
