Abstract
We proposed a fibre-optic needle probe with a side-surface interface, and evaluated the normalized received power as the ratio of the signal power to source power by using ray-trace simulation. Our probe with a 1mm diameter and 50-mm length demonstrated its performance in the sensing of target objects over a surrounding space of ∼20-mm radius with a normalized received power of 0.01-10%. We also described the optimized design of the probe for use in water, and a technique used to sense targets distributed along a fibre axis with simple rotation of the probe.
