Refractive Index Sensor for Fluid Analysis

摘要: A refractive index sensor having one or more sources, an adaptive optical element scanner, imaging optics, a sensing optic, and detectors. The scanner impinges signal from the source into optic onto sensor-sample interface at sequential angles of incidence. detector response increases dramatically to signals reflected corresponding reflection equal greater than critical angle. also uses input lens between output detector. processor controls can determine refraction fluid sample based on scan rate. be used in several operational environments laboratory downhole tool, such as formation tester properties borehole environment.
