ABSTRACT:
Mechanical translation tips can be attached to a fiber version of a frequency chirped interferometric displacement sensor. The mechanical tips can be used in noisy or deleterious environments that preclude the use of non-contact optical sensors. These tips can also be used with a hydraulic amplifier to increase the resolution of the sensor to less than one micron.
