What is remote optical spectroscopy?

Remote optical spectroscopy is a technique used to analyze the composition and properties of materials from a distance by measuring the interaction of light with those materials. This method is often used in fields such as environmental monitoring, astronomy, and industrial inspection, where it may not be practical or safe to collect samples directly. By observing how different wavelengths of light are absorbed, emitted, or scattered, scientists can identify substances and gather important data without physical contact. Remote optical spectroscopy typically employs devices such as spectrometers, which can be operated from afar using fiber optics, drones, or satellites. This technology enables rapid, non-invasive analysis over large or hard-to-reach areas.
