Abstract: Segmented Adaptive Optic Mirrors have been developed, fabricated, and demonstrated in real time atmospheric compensation systems. Until recently, most Segmented Adaptive Optic Mirrors have been designed for single wavelength applications and have not required more than 1.5 $mu of surface motion since absolute phasing of the surface is not required for very narrow bandwidth compensation. Requirements for astronomical and imaging systems have required the design and fabrication of long stroke (6 - 10 $mu@) segmented mirrors capable of absolute phasing of the segments, optical response from 0.4 to 3.5 $mu and bandwidths above 2.5 KHz. !9
