Claim 4:
5. A sensor shift system comprising:
a base; and
at least two bimorph actuators attached to the base, the at least two bimorph actuators comprising at least a first bimorph actuator disposed at the base oriented in a first direction and a second bimorph actuator disposed at the base oriented in a second direction perpendicular to the first direction, each of the at least two bimorph actuators comprising:
a shape memory alloy material; and
a beam, each bimorph actuator attached to the base at a first end of the beam, a second end of the beam opposite the first end configured to be unfixed, the shape memory alloy material electrically coupled with the beam between the first end of the beam and the second end of the beam to configure the shape memory alloy material to receive a current to actuate the shape memory alloy material; and

a sensor carriage coupled to the at least two bimorph actuators and configured to move in at least two axes in response to actuation of the at least two bimorph actuators.
