NASA¿s Origin Program strategic plans call for direct imaging optical telescopes to evolve from 8 to 30 to 100 meter apertures by 2025. Indirect measurements using long baseline interferometers require Angstrom level precision for long durations. High data rate communications for spatial acquisition and tracking systems require active mirrors and up-down transmission compensation. Fundamental to NASA¿s vision of the future is high-density deformable mirrors which enable highly corrected optical systems and structures in space. These high-channel count deformable mirrors use very high-density actuator arrays and new 3D ceramic fabrication techniques to allow contrast enhancement for planetary imaging and correct system-wide optical errors within the telescope. The large, lightweight structures envisioned demand ultra high-density deformable mirrors. These will perform the necessary correction without sacrificing size or weight. Xinetics Photonex mirror modules have demonstrated 1 mm actuator spacing with array size of 21 x 21. Larger modules with arrays up to 128 x 128 will greatly simplify the optical systems and provide even greater capabilities. Xinetics proposes developing a 32 x 32 array of actuators with 0.5 mm spacing. This will significantly enhance the current capabilities by providing over 1.3 times as many actuators in only 75% of the size.
