Abstract

A fiber-optic probe includes first and second optical fibers disposed in a body, a liquid sampling region between ends of the fibers and a reflector, and apertures communicating with the sampling region. The probe may be inserted in media in a vessel. Optical signals are transmitted through the first fiber, the sampling region and second fiber. The sampling region is offset from other parts of the probe so that bubbles or particulates flow out from the sampling region without being obstructed by the probe.
