The successful development of high-speed actuators for impact printing requires, for the evaluation of prototypes, a reliable and convenient technique to measure small, rapid displacements of mechanical parts. Ideally, the measurement technique should be linear, should interfere minimally with an actuator's dynamic performance, should accommodate easily a variety of prototype designs, and, for multi-piece actuators, should be able to monitor the motion of each piece independently.
