optical delay line

An optical delay line is a device used to precisely control the timing of light signals in optical systems. It works by lengthening the path that light travels, effectively delaying its arrival at a destination. This is achieved by guiding the light through a carefully measured fiber optic cable or optical components. Optical delay lines are essential in applications like telecommunications, laser systems, and scientific experiments where precise timing and synchronization of light pulses are critical. By adjusting the length of the optical path, engineers can control the delay to match system requirements without disturbing the light’s properties.
