Abstract
A spectroscopic sensor apparatus based on an all optical fiber platform includes a light source, a sensor head, and a fiber acousto-optic tunable filter (FAOTF) based spectrometer. The target agent to be detected interacts with the optical field through the sensor head and produces an absorption or emission spectrum. The absorption or emission spectrum is then measured by the AOTF spectrometer to analyze the constituent of the target agent.
