(a) Model geometry for the cantilevered adaptive mirror held for horizontal beam deflection. Clamping on the right-angled portion of the L-shaped substrate is intended to minimize surface distortion. The dashed line indicates the axis of pitch rotation, passing through the central ray of the incident beam footprint. The magenta arrow shows the incident light direction. (b) A cross section shows the positions of the four symmetrically placed piezoceramic elements. All units are mm. |
