What is Optical Sensing?
Optical sensing refers to the technique of using light-based sensors to detect changes in an environment, substance, or object. These sensors typically use infrared, visible, or ultraviolet light to measure parameters such as distance, temperature, pressure, composition, or motion.
The basic principle involves:
Emitting light onto a target
Measuring changes in light intensity, wavelength, or phase
Converting this change into an electrical signal for interpretation
