Abstract

Background. The research object is fiber-optical pressure sensors (FOPS) with an open optical channel (OOC). The research subject is designing of FOPS with metrological characteristics meeting the requirements for fiber-optical informationmeasuring systems of rocket-space and aircraft equipment. The goal of the research is to develop a complex approach to development of theoretical, scientific-technical and technological foundations of FOPS development. Thus, the problem of creation of a scientific conception of FOPS designing is a topical one.
Materials and methods. It is suggested to improve the reliability of FOPS within rocket-space and aircraft equipment by excluding mechanical informative and noninformative curves of a fiber-optical cabel, which is possible through application of open optical channels of FOPS measuring transducers. In order to unify circuitconstructive solutions of fiber-optical transducers of linear and angular microdisplacements of reflection and attenuator types the author uses phenoma of reflection, interruption, refraction.
Results. The author has developed а new conception of differential FOPS designing for fiber-optical information-measuring systems of rocket-space and aircraft equipment, disntiguished by taking into account spatial distribution of luminous flux in the far diffraction zone of fiber-optical transducers, used in FOPS as base elements of fiber-optical transducers of linear and angular microdisplacements of reflection and attenuator types with OOC.
Conclusions. The author has determined the complex approach to designing FOPS with OOC for prospective fiber-optical information-measuring systems, providing dicreased time and material costs of design and implementation, as well as improved metrological and operational characteristics by exposing sources of possible errors.
