A linear actuator has a base, a linear guide coupled to a flat, planar side of the base and extending in a travel length of an object to be moved, a contact plate extending along the flat, planar side of the base, and a carriage. The carriage includes an enclosure formed of an acoustically isolating material, a moving element configured to move along the guide and is coupled to the enclosure, a piezoelectric element including a contact site in physical contact with the contact plate, and a housing elastically holding the piezoelectric element, the housing coupled to the enclosure with no direct contact with the moving element. An electrical power source is in electrical communication with the piezoelectric element, wherein the power source energizes the piezoelectric element to effectuate movement of the carriage along the linear guide via the physical contact between the contact site and the contact plate.

A rotational and translational microposition apparatus includes a first rotary motor, a second rotary motor and a linear motor. The first rotary motor surmounts an upstanding bracket mounted to a support surface. A rigid link having a right angle bend formed in it interconnects the first and second rotary motors to one another. A first end of the rigid link is secured to an output shaft of the first rotary motor and a second end of the rigid link is secured to a mounting plate to which is secured the second rotary motor. A linear motor has an output shaft connected to the output shaft of the second rotary motor. Selective operation of the three motors enables a probe to be positioned in an infinite plurality of positions that collectively form a cone where the tip of the probe is coincident with the vertex of the cone.
