Infrared (IR) Spectroscopy: Overview

Infrared (IR) Spectroscopy: Overview

When electromagnetic radiation passes through a material, atoms or molecules transition from a lower to a higher energy state by absorbing radiation corresponding to the energy difference between the two states. The absorption of infrared (IR) radiation causes transitions between vibrational energy levels in a molecule. Therefore, IR spectroscopy is a useful analytical tool for determining the molecular structure of molecules.
Different compounds display unique properties due to their...

IR Spectrometers

IR Spectrometers

There are two main infrared (IR) spectrophotometers: dispersive IR spectrometers and Fourier transform infrared (FTIR) spectrometers. In a dispersive IR spectrometer, a beam of infrared radiation produced by a hot wire is divided into two parallel equal-intensity beams using mirrors. One beam passes through the sample, while another is a reference beam. The beams then move through the monochromator, which separates the radiations into a continuous spectrum of different frequencies. The...

The 10.6-micrometer wavelength is identified as the preferred choice.
Advantages of the 10.6-micrometer wavelength include the availability of high-power, high-efficiency continuous-wave (cw) lasers, coherent receiver techniques, and effective haze/fog penetration.
A method for estimating laser power was developed, with area scan rate as a key factor.

Conclusions:

The integration of motion sensing significantly enhances the interpretability of images generated by passive IR line-scanning radiometers.
The 10.6-micrometer wavelength offers distinct advantages for this application, facilitating robust system design and performance.
The proposed laser power estimation method provides a simplified approach for system design.
