LabVIEW-Based Automated Setup for Interferometric Refractive Index Probing

Abstract

In the paper, we explain an automated LabVIEW controlled setup that enables interferometric measurements of refractive indices in crystalline materials using a laser light source. The setup combines a mechanical system, a microcomputer-controlled gearless drive, a Michelson interferometer, an optical detector, a data acquisition system and a LabVIEW virtual instrument for an accurate non-destructive determination of the refractive index of given plane-parallel samples.We explain a concept, implementation, and hardware/software peculiarities of the developed system. Test experiments on different crystals yielded results that are in good agreement with available reference data. The range of potential applications of the proposed setup extends from fundamental optical research to biophotonics instrumentation, where efficient delivery of light is 2 of crucial importance and reliable automated probing tools are needed for optical components characterization.

Development of completion tool pressure test control system

“…There is a large safety risk in the detection, and the data obtained is prone to large errors. As shown in Figure 2, to make the test process safer and more efficient, a pressure test control system is developed for a series of safety valves [6,7]. This paper mainly introduces the software part of the detection system.…”

CdS Nanocrystallines: Synthesis, Structure and Nonlinear Optical Properties

“…Among existing methods, the electrochemical electrolysis appears to be very promising representing rather flexible and relatively simple technique [9]. Besides, different techniques for investigation of properties of new materials in optical [10,11] and millimeter-wave range [12][13][14] as well as their application for electro-optics and photonics [15,16] can be applied.…”
