A lightweight active mirror. A first layer has a front side and a backside. A
second
layer has a front side and a backside. The backside of the second layer faces the
front side of the first layer. A reflective surface is on the front side of the
second layer. The reflective surface is operable to reflect desired wavelengths
of electromagnetic radiation. A plurality of electroactive actuator strips arranged
between the first layer and the second layer are operable to alter a curvature
of the mirror. Electrical connectors are operable to cause the electroactive strips
to alter the curvature of the mirror. A plurality of stiffening elements interconnected
with at least one of the first layer and the second layer are operable to stiffen
the mirror. A plurality of shape retaining elements attached to at least one of
the first layer and the second layer are operable to deploy the mirror and to bias
the mirror in a desired position.
