Abstract
A pulse measurement device is provided, including a first signal source, a second signal source, two microwave resonators, two mixers, and a signal processing unit. The first signal source and the second signal source output a first high-frequency signal and a second high-frequency signal, respectively. Each of the microwave resonators generates an electric field according to the first high-frequency signal, and senses a variation in the electric field which is interfered by a pulse to obtain a sensing signal. Each of the mixers is coupled to one of the microwave resonators, to mix the sensing signal and the second high-frequency signal to output a down-converted signal. The signal processing unit respectively demodulates amplitudes of the down-converted signals of the two mixers to obtain amplitude signals.
