Abstract:
A multi-actuator device that is insensitive to thermally-induced position shifts between actuators, comprising:a support; a plurality of actuators, including a first actuator fixed to the support and at least one other actuator; at least one connection structure, each respective connection structure connecting the first actuator to a corresponding one of the at least one other actuator, each connection structure comprising a plurality of links, including at least a first link connected to the first actuator and a second link connected to that one of the at least one other actuator, wherein the plurality of links are formed of at least two different materials, each material having a coefficient of thermal expansion, lengths of the plurality of links and the coefficients of thermal expansion cooperating to substantially maintain the other actuator at substantially the same distance from the fixed actuator.
