There is described a terahertz modulation system. The terahertz modulation system generally has a terahertz signal emitter emitting a terahertz signal along a path; a modulation unit having a substrate and an electromechanical transducer actuatably mounted to said substrate, said electromechanical transducer having a terahertz interacting surface in said path receiving said terahertz signal and moving in back-and-forth sequences between first and second positions relative to said path upon actuation with a modulation signal, said moving modulating at least a portion of said terahertz signal; and a terahertz signal detector downstream from said modulation unit along said path, said terahertz signal detector synchronously measuring said modulated portion of said terahertz signal using said modulation signal, and generating a differential signal indicative thereof.
