Development of a Fiber based Interferometric Sensor for Non-contact Displacement Measurement
In this paper, a fiber based Fabry-Perot interferometer
is proposed and demonstrated for a non-contact displacement
measurement. A piece of micro-prism which attached to the
mechanical vibrator is served as the target reflector. Interference
signal is generated from the superposition between the sensing beam
and the reference beam within the sensing arm of the fiber sensor.
This signal is then converted to the displacement value by using a
developed program written in visual Cµ programming with a
resolution of λ/8. A classical function generator is operated for
controlling the vibrator. By fixing an excitation frequency of 100 Hz
and varying the excitation amplitude range of 0.1 – 3 Volts, the
output displacements measured by the fiber sensor are obtained from
1.55 μm to 30.225 μm. A reference displacement sensor with a
sensitivity of ~0.4 μm is also employed for comparing the
displacement errors between both sensors. We found that over the
entire displacement range, a maximum and average measurement
error are obtained of 0.977% and 0.44% respectively.
