Abstract: A detector (200) includes an oscillation source (210), a frequency multiplier (220), a transceiver (230) and a demodulator (240). The oscillation source (210) generates a first injection signal (Vi1) with a first frequency (f1). The frequency multiplier (220) receives the first injection signal (Vi1), outputs an output signal (Vo) and receives a second injection signal (Vi2) with a second frequency (f2). The frequency multiplier (220) uses injection locking to lock a frequency of the output signal (Vo) at a multiple of the first frequency (f1), and uses injection pulling to pull the frequency of the output signal (Vo) to the second frequency (f2). The transceiver (230) transmits the output signal (Vo) and receives a received signal (Vrx) with a third frequency (f3) for updating the second injection signal (Vi2). The demodulator (240) performs a demodulation operation according to the output signal (Vo) so as to generate a displacement signal (Vd).
