    Abstract: In a laser-optical arrangement for producing signals by light scattering, obscuration or reflection, from flowing particles and/or groups of particles, which are recorded, as time-dependent voltage/current fluctuations, by means of a photodetector (9) via appropriate imaging optics (7,8,18), assignment to the degree of dispersion of the flowing system is based on a subsequent measurement (10) of the root-mean-square value, and, according to the invention, the sample stream (1) is separated from a transmitter (6,7,18) and a receiver (8,9,10) by an enveloping stream (4), and the transmitter side consists of an individual light-transmitting fiber (7) provided with a means for parallel or focused emergence of a light bundle having a diameter of the order of magnitude of the particles and/or groups of particles.

    Abstract: The cylindrical interior surface of small diameter metal tubing is optically inspected to determine surface roughness by passing a slightly divergent light beam to illuminate the entire interior surface of the tubing. Impingement of the input light beam components on any rough spots on the interior surface generates forward and backward scattered radiation components. The forward scattered components can be measured by blocking direct and specular radiation components exiting the tubing while allowing the forward scattered radiation to travel past the blocking location. Collecting optics are employed to converge the forward scattered radiation onto a photodetector generating a signal indicative of surface roughness. In the back scattered mode, back scattered radiation exiting the tubing through the entrance opening is reflected 90.degree. by a beam splitter towards collecting optics and a photodetector. Alternatively, back scattered radiation can be transmitted through a fiber optic bundle towards the collecting optics. The input light beam can be supplied through a white light fiber optic bundle mounted coaxial with the first bundle.

    Abstract: A technique for gathering specific information from various remote locations, especially fluorimetric information characteristic of particular materials at the various locations is disclosed herein. This technique uses a single source of light disposed at still a different, central location and an overall optical network including an arrangement of optical fibers cooperating with the light source for directing individual light beams into the different information bearing locations. The incoming light beams result in corresponding displays of light, e.g., fluorescent light, containing the information to be obtained. The optical network cooperates with these light displays at the various locations for directing outgoing light beams containing the same information as their cooperating displays from these locations to the central location. Each of these outgoing beams is applied to a detection arrangement, e.g., a fluorescence spectroscope, for retrieving the information contained thereby.

    Abstract: A fluid particle sensor for measuring and counting particles contained in a fluid. The fluid particle sensor comprises a first bundle of generally parallel elongated fiber optics, the first bundle having a longitudinal axis and opposite inside and outside ends, and a second bundle of generally parallel elongated fiber optics, the second bundle also having a longitudinal axis and opposite inside and outside ends. The sensor also comprises means for supporting the first and second bundles such that the longitudinal axes of the first and second bundles are approximately colinear, and such that the inside end of the second bundle is closely spaced apart from the inside end of the first bundle to form a gap through which the particle containing fluid flows. The sensor further comprises means for transmitting light to the outside end of the first bundle, and means for sensing the amount of light emitted from the outside end of the second bundle.
