Focal plane scanning device

Image Number 3 for United States Patent #4708420.

A focal plane scanning device arranged to move a mirror in an optical scanning apparatus, such as an infrared scanner, including a mirror, that is connected to a support by a central flexure member. An additional pair of flexure members are provided, each of which are attached at one end to piezoceramic drive elements and at their second ends to an adjustment bracket that bears against the rear side of the mirror. The piezoceramic drive elements are attached at their second ends to the support. When the piezoceramic members are energized, a balanced movement of the mirror about the first flexure member results.
