Paper Abstract

Discrete, bimorph actuators have been designed at Itek for a deformable mirror, which has a dilatation sensitivity of 6 microns at 1.5 KV. The bimorph actuators, mechanically designed to accommodate flexibility while bending, provide surface deformation, which depends upon the actuator length and faceplate stiffness. Mechanical resonances have been measured at frequencies well above bandwidths required for wavefront correction. Life test data indicates that less than λ/5 PP wavefront change occurred after exercising the bimorph device for 100 hours at 6 microns.
