Infrared (IR) Spectroscopy: Overview

7.6K
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 Frequency Region: Fingerprint Region

2.4K
IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the...

    Summary

    This study shows that remote photoplethysmography (rPPG) in the infrared spectrum is feasible for accurate pulse extraction. Both single and multi-camera setups demonstrated effectiveness, even with significant subject motion.

    Area of Science:

    • Biomedical Engineering
    • Optical Sensing
    • Physiological Monitoring

    Background:

    • Remote photoplethysmography (rPPG) enables non-contact pulse signal extraction using standard cameras.
    • Expanding rPPG to the infrared spectrum can enhance its applicability in various scenarios.

    Purpose of the Study:

    • To investigate the feasibility of infrared rPPG using different camera setups.
    • To evaluate the motion robustness and accuracy of infrared rPPG systems.

    Main Methods:

    • Two camera configurations were tested: a tri-monochrome camera setup and a single RGB camera with a filter.
    • A benchmark dataset with diverse motion and skin tones was used for validation.
    • Dedicated LED illumination with dual wavelengths was explored to improve motion robustness.

    Main Results:

    • Both camera setups achieved accurate pulse extraction across various motion conditions.
    • The single RGB camera setup showed superiority in scaling scenarios, potentially due to reduced parallax.
    • Average signal-to-noise ratios (SNR) of +6.45 dB and +7.26 dB were recorded.

    Conclusions:

    • Infrared rPPG is a viable technique for accurate pulse measurement, even under challenging motion conditions.
    • The single RGB camera setup offers advantages in specific scenarios, particularly those involving scaling.
    • Further improvements in motion robustness can be achieved with optimized illumination strategies.
