interferometric sensors

Interferometric sensors are devices that detect changes in physical conditions—such as temperature, pressure, or strain—by measuring how these changes affect the pattern of light waves. They work by splitting a light beam into two paths, with one acting as a reference and the other interacting with the environment. When conditions change, the light waves alter their relationship, creating an interference pattern that can be precisely measured. This pattern shift indicates the specific change in the environment, enabling highly accurate and sensitive measurements for various scientific and industrial applications.
