OPTICAL ANALYTICAL SENSORS
Abstract
This article provides a brief review of optical analytical sensors, their development history, and capabilities. Sensors allow to collect, correct, transfer, process and distribute information about the state of physical and chemical devices. Chemical sensors and various spectroscopic methods used to measure the concentration of substances are briefly discussed. Several special fiberoptic light-transmitting sensors, including conductive polymer fibers, light transmission of optical fibers, reflection imaging in an optical fiber based on the corpuscular model of radiation are reviewed. In addition, the capabilities of the optical reflection device mini-spectrophotometer Eye-One Pro to measure wide-range diffuse reflectance coefficients and colorimetric properties of samples, their structure, determination of substance concentrations in environmental objects, their use in production, management of industrial processes were summarized.
