Diaferometer: a measuring instrument for determining the difference in optical paths
A diapherometer is a measuring instrument that is used to measure the difference in optical paths between two beams of light. It is often used in optics and physics to measure light parameters and determine the properties of optical materials.
The name "diapherometer" comes from the Greek words "diaphero" (to carry, pass through something) and "metreo" (to measure, determine). Consequently, a diapherometer determines the difference in optical paths that pass through an optical system using various measurement methods.
There are many different types of diapherometers that use different methods to measure optical path differences. Some diapherometers are based on the interference of light, while others are based on the refraction of light. Some measure optical path differences using optical grids or prisms, while others use mirrors or translucent planes.
One of the most common types of diaferometers is the Michelson interferometer, which is used to measure the difference in optical paths between two beams of light. This device was developed by the American physicist Albert Michelson at the end of the 19th century.
Another common type of diapherometer is the Fabry-Perot interferometer, which is used to measure the wavelengths of light. This device was developed by French physicists Charles Fabry and Alphonse Perot in the 19th century.
Diaferometers are widely used in scientific research, as well as in industry, for example, for quality control of optical materials and the production of optical instruments. They are also used in medicine to measure vision and diagnose eye diseases.
In conclusion, we can say that a diapherometer is a very important and useful measuring instrument that is used in many fields of science and technology. Its wide range of applications and high measurement accuracy make it an indispensable tool for many research and industrial processes.
Diapherometer - (from the Greek diaphero - “to carry, pass through something” and metreo - “to measure, determine”) - a device for automatically measuring and recording the amount of energy transferred through an electrical circuit.
Diaferometer is also called automatic energy meter. It is designed to measure active and reactive electrical energy in single-phase and three-phase AC circuits.
The operating principle of a diaferometer is based on the conversion of measured electrical energy into voltage pulses, the frequency of which is proportional to the power value. Pulses are counted by a counter, the readings of which are used to determine the amount of energy.
Diaferometers are widely used in commercial and technical electricity metering systems at industrial enterprises, power system facilities and by household consumers.
