METHOD AND DEVICE FOR SIGNAL PERIOD STRETCH AND ULTRA-FAST SERIAL-TO-PARALLEL/PARALLEL-TO-SERIAL CONVERSION

摘要

Disclosed are a method and a device for signal period stretch and ultra-fast serial-to-parallel/parallel-to-serial conversion, which relate to the technical field of analysis and measurement control. The method is to change a propagation velocity of a target signal or displacement-reflecting the target signal, so as to extend or compress the period of the signal. Displacement-reflection is to generate a Doppler shift through interaction of the displacement of a reflecting plate with the target signal, so as to achieve period stretch; for a signal transmitted through a medium, the propagation velocity of the target signal is changed by changing the property of the medium, so as to achieve period stretch; for a signal ascribed to an electron flow, the movement velocity of the electron beam is changed through a varying acceleration field, so as to achieve period stretch. A target signal condensing/diffusing and collimating lens, a synchronous signal controller and a plurality of period stretch devices are utilized to achieve ultra-fast serial-to-parallel/parallel-to-serial signal conversion. Thereby, a device that originally cannot work at the frequency spectrum of the target signal is enabled to observe, transmit and parse content of the original target signal.
