Abstract

The invention discloses a second harmonic balance detection-based time jitter delay measurement device, which comprises a first half transparent and half reflecting mirror, a second harmonic generation medium, a second half transparent and half reflecting mirror, a time delay line, a first photoelectric detector, a second photoelectric detector, a differential circuit, a third half transparent and half reflecting mirror, a first reflector, a second reflector, a first focusing mirror, a second focusing mirror, a third reflector, a first to-be-measured pulse input interface, a second to-be-measured pulse input interface and a differential signal output interface. According to the technical scheme of the invention, a second harmonic balance detection mechanism is used, according to the characteristic that output of an electric signal is 0 in the case of no delay, time jitter delay is measured, a requirement that time jitter delay has a high measurement resolution is achieved, and applications to a high-precision time synchronization system are facilitated.
