摘要： An apparatus or method identifies and quantifies components of a sample medium filling a gap of an assembly of a transparent tube and a cylindrical float located substantially coaxially with the tube. This identification or quantification is made based on the high angle scatter and/or fluorescence of the medium. A polarized monochromatic or biochromatic light beam of the wavelength for which the tube is transparent projects through an optical focusing and/or scanning system to illuminate a section of the gap with a line of light positioned parallel to the longitudinal axis of the tube but displaced laterally therefrom. Means position and rotate the tube about its longitudinal axis producing a complete circumferential illumination of the sample medium sections in the gap. Light filtering and detecting means normal to the illumination axis detects high angle light scattering properties and/or fluorescence properties from the sample medium. Signal processing means analyzes the output from the detecting means to identify and quantify the sample medium.

摘要： An apparatus or method determines the gap between an assembly of a tube and a cylindrical float located substantially concentric to the tube. An elliptically polarized light beam at the wavelength for which the materials of the tube and the gap are transparent or translucent is along an optical axis. The index of refraction of the tube and float materials are greater than the index of refraction of the gap material. Means translates and rotates the assembly along and about its longitudinal axis producing an illumination. A light filtering means along the optical axis beyond the assembly blocks light of the illumination reflected by the assembly and refracted by the tube, the gap between the tube, and the float and the float and transmits light of the illumination refracted by the tube and the gap between tube and float. Light detection means receives transmitted light and signals a signal processing means. The method has steps of transmitting the monochromatic beam of elliptically polarized light along the optical axis to the assembly, focusing the beam of light, translating and rotating the assembly through the light, producing an illumination, filtering the illumination by blocking illumination reflected by the assembly and refracted by the float, the tube and the gap between the tube and the float and transmitting the illumination refracted by the tube and the gap between the tube and the float.
