ABSTRACT:
A device for remote sensing utilizing fiber optic techniques is presented. This device makes use of multi-mode optic fibers in conjunction with light polarized in multiple directions. The device presents a platform which is insensitive to phenomena outside of the remote sensing region while capable of detecting and analyzing multiple phenomena within the sensing region. The device is also capable of inspecting multiple remote sensing regions simultaneously.
