Projectors 15 meters or more in diameter and of excellent quality will be needed to successfully transmit laser beams from the earth to satellites in space. They can be made up of adaptive optic mirror segments one or two meters in diameter connected to make a phase-continuous mirror surface. Since they must be used in poor as well as good seeing conditions, the faceplate influence function radius must be short and the actuators closely enough spaced to use with Fried coefficients of 2 to 4 cm. Under a Phase II NASA program we are developing a lightweight prototype adaptive optic mirror segment meeting these requirements. It uses a graphite impregnated composite cyanate ester faceplate. Design and materials considerations will be discussed. [ABSTRACT FROM AUTHOR] |
