ABSTRACT:
An optical biprobe for observing a flow in any direction in a diphasic emulsion is provided. In a preferred embodiment, the optical biprobe comprises a support which is capable of rotating about a first axis on which is mounted a hollow member for intruding into the emulsion. At least two optical fibers are mounted in the support such that the optical fibers extrude from the hollow member and are fixed at a predetermined distance from one another. The hollow member is pivotally about a second axis perpendicular to the first axis. Completing the biprobe is an actuator for controlling the pivoting of the hollow member about the second axis.
