Accurate Air Refractive Index Measurement Using Intomation-Type Laser Hindrance Method

Abstract

This research introduces a new way to measure how light behaves when it passes through air. The method uses a special kind of laser that produces two different beams of light with different colors. These beams are sent into a device called a Michelson interferometer, which splits the light and measures how it interacts with air. The device has detectors that receive the light signals and a special quartz vacuum chamber that helps with the measurements. By moving a certain part of the device and measuring the changes in the light signals, we can determine the refractive index of air. This method is very accurate and can withstand outside influences, which makes it useful for precise measurements and other technical fields that involve lasers and light.
