Abstract: A drive mechanism including a rotary actuated motor configured to rotatably drive a drive arm between a first position to a second position and an actuator responsive to movement of the arm, wherein the actuator is thermally isolated from the arm in both the first position and the second position to create a thermal barrier. The drive arm is configured to engage and advance the actuator between the first position and the second position, while remaining physically spaced from the actuator in the first position and the second position. The drive arm includes a recess such as an opening, wherein the actuator has a member configured to reside in the recess and remain thermally isolated from the arm in both the first position and the second position. In one preferred embodiment, a shutter of an imaging device is positioned in response to the actuator, which shutter remains thermally isolated from the motor and arm. Other devices may be driven as well, such as switches.

Abstract: A method includes creating a gas flow in a gas cell and cooling a portion of the gas flow to create a thermally-induced temperature gradient in the gas flow. The method also includes directing at least one laser beam through at least a portion of the gas flow with the thermally-induced temperature gradient. The gas flow can be directed axially along a length of the gas cell or transverse to the length of the gas cell, and the at least one laser beam can be directed axially along the length of the gas cell through at least the portion of the gas flow. The gas flow may represent a first gas flow, and the method may further include creating a second gas flow in the gas cell and cooling a portion of the second gas flow to create a thermally-induced temperature gradient in the second gas flow.

Abstract: A drive mechanism having a bi-stable motor driving an actuator with a high starting torque, and a slower, regulated velocity as the actuator moves through its range of travel. This advantageously maintains high torque margins at low velocity, and lowers the kinetic energy of the bi-stable actuator at end of travel by limiting the terminal velocity and establishing a softer stop. A solenoid may be used in one embodiment. Actual bi-stable motor values are obtained immediately before the move to maintain accurate control of the motor, such as the resistance and inductance of the motor coil. For instance, the bi-stable motor may be driven into a stop, and the coil resistance may be calculated by sensing current associated with the calibration voltage. Inductance may be measured similarly by applying low level AC currents. Back-emf is sensed through the coil resistance, and an estimated motor rotation rate is sent to a feedback loop to maintain the desired rate.

Abstract: A method, apparatus and system for profiling a material composition of a volume is disclosed. A beam source directs a pulsed beam of electromagnetic energy from into the volume. A plurality of backscattered beams is received at a detector. The plurality of backscattered beams is generated from a plurality of depths within the volume in response to interactions of the directed pulsed beam at the plurality of depths. A processor performs range gating of the plurality of backscattered beams to obtain a depth profile of backscattered intensity within the volume and estimates a material composition at different depths of the volume from the generated depth profile.
