Infrared techniques encompass a broad range of methods that utilize infrared radiation for analysis and imaging. Infrared light, located in the electromagnetic spectrum between visible light and microwaves, is often associated with heat. However, its applications extend far beyond thermal detection. One of the most common infrared techniques is infrared spectroscopy. This method analyzes the absorption and transmission of infrared radiation by a sample. Different molecules absorb specific wavelengths of infrared light based on their vibrational and rotational modes, creating a unique spectral fingerprint. This allows for the identification and quantification of chemical compounds. Another significant application is infrared thermography, which creates images based on the infrared radiation emitted by an object. This is widely used for detecting temperature variations, making it valuable in fields like building diagnostics for insulation leaks, medical imaging for inflammation, and industrial monitoring for equipment malfunction. Infrared imaging cameras capture this emitted radiation and translate it into visual representations of temperature. Further infrared techniques include Fourier-transform infrared spectroscopy (FTIR), which offers improved resolution and speed compared to traditional dispersive methods, and near-infrared (NIR) spectroscopy, used for analyzing organic compounds. These techniques are non-destructive and versatile, finding applications in chemistry, physics, biology, medicine, and engineering.
