Fourier transform spectroscopy

Fourier transform spectroscopy is a technique used to analyze light and other electromagnetic signals to identify the composition of materials. It works by measuring how a sample interacts with different frequencies of light. The data collected is converted into a spectrum using a mathematical process called the Fourier transform, which reveals the specific wavelengths absorbed or emitted by the sample. This information helps scientists understand the chemical and physical properties of substances, aiding in fields such as chemistry, environmental science, and astronomy. Essentially, it allows us to "see" the unique fingerprint of materials through their interaction with light.
