Abstract:
According to a method for cavity enhanced microscopy, a sample is arranged on a sample carrier of an optical cavity, which is formed by a pair of opposing mirrors. A description defining a lateral motion of the sample during a predefined time interval and a variation of the cavity length during the time interval in a temporally synchronized manner is stored and an actuator system is triggered to move the sample carrier and/or at least one mirror of the pair of mirrors to effect the lateral motion of the sample with respect to the cavity and the variation of the cavity length according to the description. Light is introduced into the cavity and transmitted portions and/or reflected portions and/or scattered portions and/or emitted portions are detected to generate a sensor dataset.

Abstract:
A device for automatically analyzing samples by a colorimetric procedure may be particularly used for blood analysis. A reaction ring bearing at its periphery an array of transparent reaction cups is stationary. An optical fiber is mounted on a rotating disk, concentric with the reaction ring and downwardly oriented with respect to the top of a cup, the optical fiber having one end at a central location where it receives light from a stationary light source and its other end opposite a bottom of a reaction cup in alignment with a measuring photomultiplier.
Abstract:
Subsurface contaminants are readily and inexpensively detected and measured by means of a test head positioned at the subsurface site and forming a protected test chamber for the liquids to be tested. The head encloses the end faces of fiber optic elements which carry radiation to the liquid sample from a test instrument located at the surface and which return radiation from the sample to the instrumentation. A connector positioned at the surface decouples the head from the instrumentation, so that the same instrumentation can service a larger number of test sites.
