Fundamentals of design of jet-drop optical systems for three-coordinate measurements of electric, magnetic and gravitational field strengths by the pendant drop method. Part 1

Abstract

The article discusses the principle of operation and
the main components of jet-drop optical measuring
systems (JDOMS) based on the pendant drop method for
monitoring electric field strength (EFS), magnetic field
(MFS) and gravitational field (GFS).
To make a pendant drop sensitive to electric or magnetic
fields, it is proposed to charge it electrostatically or to
create it from a magnetic fluid, and its mass allows you
to feel changes in the gravitational field. The use of
magnetic fluids as the basis of a pendant drop is the most
multifunctional for measurements of EFS, MFS and GFS.
The implementation of the zero measurement method
using a pendant drop as a comparison device, a null
organ that perceives the difference in the effects of the
measured and reference field(s) at the level of quasi-zero
three-coordinate displacements, is considered. They are
measured by high-precision optical measurement methods.
Different variants of modern optical measurement systems
are analyzed.
