Coherent Optical Sensors

Coherent optical sensors are devices that detect changes in light waves with high precision. They work by mixing a reference light signal with the incoming light from a target, allowing the sensor to measure minute variations in phase, frequency, or amplitude. This technique enables highly sensitive detection of things like vibrations, temperature changes, or motion. Coherent sensors are used in applications such as biological imaging, environmental monitoring, and industrial inspection, because they can provide detailed, accurate information about the properties of the object or environment being studied, often surpassing traditional optical sensing methods.
