US 4,707,134 A · Fiber optic probe

Abstract

A fiber optic probe having a sealed, cylindrical housing closed at one end by a transparent window and at the opposite end by a wall through which a plurality of optical fibers extend toward the window. Adjacent the window the fibers are radially and circumferentially spaced about the axis of the housing and converge along lines which intersect one another at a common point on the housing axis that is adjacent or beyond the outer surface of the window. At least one of the fibers transmits light from a source through the window to illuminate a zone of a fluid sample, whereby particles present in such zone scatter light therefrom to the remaining fibers for transmission through the probe housing to light detecting and measuring apparatus.

Dependent claims

A fiber optic probe comprising a housing having a longitudinal axis;

a transparent window closing one end of said housing and having inner and outer surfaces;
and a plurality of elongate optical fibers within said housing and constituting all of the optical fibers within said housing, all of said fibers having their corresponding ends terminating adjacent and confronting the inner surface of said window and extending in a direction away from said window through and outwardly of said housing, said corresponding ends of all of said fibers being radially spaced from the axis to said housing and circumferentially spaced from one another, said corresponding ends of all of said fibers having their longtitudinal axes converging toward one another in a direction toward the outer surface of said window and intersecting one another at a common point on the axis of said housing.
