Controlled time delay signal constrain transfer conveying systems

The present invention provides a controlled delay signal constraint transmission system, relating to technical field of all optical signal process, resolving the problem of avoiding the electromagnetic interference of the delay system; the optical structure of the transmission system includes: uv or uv emitted by a laser is divided into a directly transfer beam and a frequency shift beam by a light splitter, the directly transfer beam and the frequency shift beam across form a beat interference after collimator and extender respectively, and sidely written into fibre etched with mask to form an interference fringe at a certain interval, forming a moving grating set which grating distance is millimetre-sized; the moving speed of the cavity mirror is relative to the frequency difference of the frequency shift beam; an optical pulse signal is coupled to input in the moving grating set, and constraining in the moving grating set by a round-trip vibration, transmitting to an output by a determined speed, then coup
