The application discloses a cross-water bridge parameter inversion method and system based on generalized compact polarization SAR total power intensity peak value, and belongs to the technical field of synthetic aperture radar remote sensing, and solves the problems of low system efficiency, non-movable discriminator, non-uniform GCP mode discriminators and precision affected by pixel deviation of the prior art. The application obtains or synthesizes a received scattering vector; total power is calculated pixel by pixel based on the received scattering vector, a filter is used for multi-view processing, a smoothed total power map is obtained, the smoothed total power profile in the distance direction is obtained by averaging in the azimuth direction within the azimuth direction interval covered by the determined bridge main span, three local maximum peak values satisfying preset conditions are identified by using a peak value detection method; and the geometric parameters of the bridge are inverted based on the pixel positions of the local maximum peak values and combined with imaging geometric parameter inversion. The application is used for the safety monitoring and quantitative inversion of geometric parameters of cross-sea and cross-river bridge infrastructure.

The application discloses a device and method for detecting the motion of a particle captured in an optical trap. Transmission light is emitted from a transmission light source, and the transmission light is incident on an optical waveguide. The optical trap capturing light and the particle are arranged on the circumferential side of the optical waveguide, the particle is captured by the optical trap capturing light, the transmission light in the optical waveguide is coupled into the particle and then coupled back into the optical waveguide, and finally incident on a power detector. The transmission light, the particle and the waveguide form an acoustic-optic system. The waveguide is fixed, and at this time, the motion of the captured particle will change the relative distance between the two, and then change the transmittance of the transmission light in the waveguide, so as to calculate the motion information of the captured particle, and realize the detection of the motion of the particle captured in the optical trap. The application can greatly reduce the optical path complexity and volume of the particle motion detection module in the optical trap system, reduce the coupling of the motion signals between the axes of the particle, greatly reduce the light power intensity required for detecting the motion of the captured particle, improve the detection efficiency, and has practical application value.

It is proposed a method and device for the realization and reaching the required parameters for a nuclear reaction of light nucleus in liquid. The time for the plasma sustainability is achieved by excitation of long train of high peak intensity ps pulses. The preliminary estimations show a power intensity of 1019 - 1020 W / cm2 ( corresponding for the wavelength of 1064nm is round 5.1011 V / m electric field ). It is observed, that the emission of the D ions at 656nm continues after the end of the excitation and ions recombination life time, which leads to the conclusion that a high energy exothermal reaction is triggered.
