An automatic interference refractometer.
Interference refractometry is a well-established method of determining the concentration of anaesthetic agents in gas mixtures. A photo-electric detector system has been fitted to a small portable, direct-reading interference refractometer to display automatically the concentration of the agent being measured. The design of the instrument is described and two possible methods of information dis...
متن کاملAll-fiber multimode-interference-based refractometer sensor: proposal and design.
A novel all-fiber refractometer sensor is proposed, which is based on multimode interference in the multimode fiber core section sandwiched between two single-mode fibers. A wide-angle beam propagation method in the cylindrical coordinate is employed as the modeling tool for simulation and design of the proposed refractometer sensor. The design for a refractometer is presented that shows that t...
متن کاملThe Interference Microscope as a Refractometer for Liquids
Determination of the refractive index of liquids by the interference microscope was made possible by the use of a specially constructed holder for the liquid. This ensures a permanent lateral separation between the reference and the object areas and, as the depth of the object area is continuously increasing, a system of fringes is observed. The spacing of the fringes is a function of the refra...
متن کاملInterference Sensitivity of an Automatic Modulation Classifier
− In this paper, the experimental evaluation of the prototype of an automatic digital modulation classifier, carried out in a shielded chamber, is described. In this particular environment, immune to external interference, the prototype has been tested against different types of out-ofband RF interfering signals, in order to assess its robustness. The results present good success percentages wi...
متن کاملAn Automatic Fingerprint Classification Algorithm
Manual fingerprint classification algorithms are very time consuming, and usually not accurate. Fast and accurate fingerprint classification is essential to each AFIS (Automatic Fingerprint Identification System). This paper investigates a fingerprint classification algorithm that reduces the complexity and costs associated with the fingerprint identification procedure. A new structural algorit...
