Paper Abstract
In this work, we consider optimal design of Modal Power Distribution (MPD) based fiber optic sensors and compare
power-meter and CCD camera based techniques for strain measurements. To the best of authors' knowledge, majority of
the power-meter based MPD sensors use a single photo detector, and there is only one known work where two photodetectors
are used with no optimization on photo-detector locations. Optimal measurement location selection problem
and comparison of power-meter and CCD camera based sensor measurements were both addressed in this work. Based
on our experimental data, more than 100% increased sensitivity is observed in the newly designed optimal strain sensor.
It was also shown that there is a fixed nonlinear relationship between CCD based and power-meter based fiber optic
sensor measurements. This allows estimation of power-meter measurements utilizing CCD camera images, which in turn
simplifies the optimal detector location selection problem.
