Latest Patents

Xiangdong Ma holds a patent for an all-optical ultrasonic detection device based on light-induced ultrasound and laser interference. This device features a first laser connected to an optical switch, which in turn is linked to a dielectric film. A second laser generates both a reference laser beam and multiple detection laser beams. The reference laser beam produces a first frequency-shifted reference laser beam along with several second frequency-shifted reference laser beams. The first frequency-shifted reference laser beam generates a carrier signal. The detection laser beams are reflected by the dielectric film and interfere with the second frequency-shifted reference laser beams. The resulting interference light passes through a fourth fiber coupler and reaches a second photodiode, generating a frequency-modulated signal. This signal, along with the carrier signal, is input to a frequency mixer to produce a mixed signal. An acquisition unit is designed to obtain a vibration signal for the object to be detected. Xiangdong Ma has 1 patent to his name.
