Abstract: Provided are a method and a device for fast focusing by directly detecting target moments. The method includes: generating a setting modulation matrix and loading the modulation matrix to an optical modulator, receiving an optical signal emitted or transmitted by a target object at a current focusing position, and modulating, by the modulation matrix, the optical signal; acquiring a geometric moment value of the target object at the current focusing position according to the modulated optical signal; calculating a central moment; and a focusing position, obtained by refocusing, serving as the current focusing position, returning the optical signal of the target object that is received at the current focusing position and emitted or transmitted by the target object, comparing the central moment corresponding to the target object at all the focusing positions, and determining the focusing position that corresponds to the minimum central moment as the focusing position.

Abstract: An electronic current transformer for measuring currents includes a shielding structure, TMR sensor, conductor, amplification circuit, and circuit board. The shielding structure comprises a material that protects the sensor from external disturbance and damps the magnetic field from the internal conductor. The TMR sensor is connected to the amplification circuit for electric current measurement by means of reconstruction of magnetic field measurement. The TMR sensor is configured to receive data from the conductor and to transmit the data to the amplification circuit, which is configured to amplify the data and release the data as an output of the transformer.
