Magnetic dichroism measuring instrument of magnetic liquid

Abstract

The invention discloses a magnetic dichroism measuring instrument of magnetic liquid. The measuring instrument mainly comprises a light source L, a beam splitter mirror C, a first polarizer A1, a second polarizer A2, a third polarizer A3, a lambda/4 wave plate B, a Helmholtz coil M, a detection sample S1, a reference sample S2, a first photoelectric probe D1, a second photoelectric probe D2, a differential amplifier H, a Helmholtz coil power supply E, and a computer control and data processing system PC. The measuring instrument directly measures relative transmission coefficients of e light of which the polarization direction is parallel with the direction of an external field or o light of which the polarization direction is vertical to the direction of the external field by adopting a principle of differential measurement, has the advantages of strong anti-interference capacity, high reliability and high sensibility, uses the existing mature technique for all critical components, and can satisfy the measurement of the magnetic dichroism of the magnetic liquid.

AI Technical Summary

Benefits of technology

This patented device uses advanced technologies that improve its performance by providing stronger resistance against interferers like electromagnets or other devices used for measuring magnectic fields. Its main technical features include improved accuracy over traditional methods while also being more reliable than older techniques such as atomic force microscopy (AFM).

Problems solved by technology

This patented describes various ways to detect changes in magnetocalence when there's no added substances present during manufacturing processes such as casting with metal molds. These techniques involve measuring how much light travels at one wavelength compared to another wavelenthus without any other materials being introduced into the process. By comparing these measurements over time, we get indications about whether some things have changed their properties like coloring or brightness depending upon factors like ambient temperatures.
