Paper Abstract

Reported is an investigation of a novel approach for producing and correcting active optical mirrors. Photoactive polymers represent a special class of "smart materials" whose electronic and physical properties such as conductivity, charge distribution, and especially shape can be changed in response to the environment (voltage, light, stress). The ability of photoactive polymers to change the structure of a polymer matrix in response to light is being studied to allow active figure control of membranes for optical element use. Photoactive substrates (mirrors) were produced. Incoherent light sources were used to effect shape control. Shack-Hartman Wavefront sensing was used to quantify the initial and optically altered figure of samples. Motion of two classes of samples was measured and is reported here. Proposed is also a new stress control technology as well as new hybrid technology combining two classes of photoactive materials.
