Note: A piezo tip/tilt platform: Structure, kinematics, and experiments

A Piezo Tip/Tilt Platform ((PTP)-P-2) is presented with its structure, kinematics, and preliminary experiments. Two essential models of the presented (PTP)-P-2, an equivalent hinge of the flexure hinge and a simplified model of the transmission mechanism, are discussed with the analysis on the structure of the (PTP)-P-2. Based on these models, the inverse kinematics of the (PTP)-P-2 is derived. Two experiments are conducted on a prototype of the (PTP)-P-2. The kinematic model is verified with experimental results, which also indicate that the resolution and the repeatability of the (PTP)-P-2 is, respectively, better than 0.50 mu rad and 0.25 mu rad.
