Abstract

Sposób pomiaru zmian pola magnetycznego w osrodku aktywnym wypelnionym parami atomowymi poprzez wykrywanie amplitudy modulacji skrecenia, osi glównej plaszczyzny polaryzacji eliptycznej swiatla w funkcji czestosci modulacji, charakteryzuje sie tym, ze za pomoca zródla swiatla (101) emituje sie swiatlo o dlugosci fali dostrojonej do przejscia pomiedzy stanem podstawowym a wzbudzonym w atomach osrodka aktywnego znajdujacych sie w komórce, które polaryzuje sie za pomoca pierwszego polaryzatora (104) i kieruje na plytke fazowa cwiercfalowa (105) z osia optyczna umieszczona pod katem od 1 do 10 stopni do kierunku polaryzacji swiatla, transformujac polaryzacje liniowa swiatla w polaryzacje eliptyczna po czym kieruje sie swiatlo na komórke z osrodkiem aktywnym (106), a swiatlo po przejsciu przez komórke odbiera sie za pomoca analizatora (108), którym jest polaryzator, którego os skrecona jest o kat w zakresie od 70 do 110 stopni wzgledem osi pierwszego polaryzatora, a swiatlo transmitowane przez analizator rejestruje sie za pomoca detektora generujacego sygnal elektryczny (109), który poddaje sie analizie czestotliwosciowej i na podstawie sygnalu kata skrecenia pólosi glównej plaszczyzny polaryzacji na okreslonej harmonicznej modulacji okresla sie zmiany pola magnetycznego. The method of measuring changes in the magnetic field in an active medium filled with atomic pairs by detecting the amplitude of the twist modulation, the main axis of the plane of the elliptical polarization of light as a function of the modulation frequency, is characterized by the fact that a light source (101) emits light tuned to the transition between the basic state and the excited state in the atoms of the active medium located in the cell, which is polarized by means of the first polarizer (104) and directed to the quarter-wave phase plate (105) with the optical axis placed at an angle of 1 to 10 degrees to the direction of polarization of light, transforming polarizations linear light in elliptical polarization, whereupon the light is directed to the cell with the active center (106), and the light after passing through the cell is received by means of the analyzer (108), which is a polarizer whose axis is twisted by an angle in the range of 70 to 110 degrees relative to the axis of the first polarizer and the light to the transm They are registered by means of a detector generating an electric signal (109), which is subjected to a frequency analysis and based on the signal of the angle twisting of the main axis of the polarization plane, changes in the magnetic field are determined on a specific harmonic modulation.
