Aspects of the Transit of a Narrow Beam of Infrared Radiation Through a Fibrous Material

Abstract

The article is devoted to the use of optical methods in the study of the properties of fibrous materials. Based on the results of an analytic investigation of the transit of a narrow beam of infrared radiation through a fibrous material we are able to determine the optimal location from the point of view of the maximum sensitivity of the source and detector of the radiation of an optoelectronic transducer where an optical sensor is used in the control system. The relationships and practical calculations obtained make it possible to quantitatively estimate the values of the propagation of radiant energy, and this may serve as a basis for structural and energy calculations of the parameters of an infrared optoelectronic transducer.
