The application provides an orbital angular momentum and wavelength dual multiplexing polarization sensitive zooming super lens based on an orbital angular momentum and wavelength dual multiplexing polarization sensitive zooming super lens, characterized in that the super lens is composed of a silicon dioxide substrate layer and a silicon elliptical nanometer column medium layer. Through an orbital angular momentum topological charge number orthogonality and wavelength selectivity dual multiplexing mechanism, combined with a polarization sensitive design, a geometric phase regulation mechanism, the silicon elliptical nanometer column array is optimized through size and rotation angle, 0-2pi full phase coverage is realized, different orbital angular momentum modes, different wavelengths and left-handed / right-handed circularly polarized incident light are precisely demultiplexed in a 400-700nm visible light band, multi-channel independent zooming can be realized, and the focusing efficiency is greater than or equal to 65%. The application solves the defects of single zooming function, limited channel capacity and poor polarization compatibility of the traditional super lens, has compact structure and high integration, and can be widely applied to the fields of miniature imaging systems, optical communication, holographic display and the like.

Systems and methods are described herein for determining information about the relative or absolute muscle fiber alignment in the depth of a tissue using polarization sensitive optical coherence reflectometry or polarization sensitive optical coherence tomography. Using the information about the muscle fiber alignment of the tissue, parameters for a pulse field based ablation protocol are determined.

The application discloses a high-precision linear polarization information measuring device, and relates to the technical field of semiconductor linear polarization light information measurement. The device comprises a detection unit module, a voltage processing module and a calculation and output module. Two groups of four detectors are connected in series through a circuit, and the maximum polarization sensitive directions of the two groups of detectors are 45 degrees apart. When linear polarization light irradiation occurs under a certain power supply bias, the detection unit module generates two voltage signals, and the generated voltage signals are only related to a polarization angle. The two voltage signals pass through the voltage processing module, and a voltage signal filtered from common mode interference is obtained through a programmed gain voltage amplifier and a difference processing circuit. Finally, the processed voltage signal is transmitted to the calculation and output module. A calculation unit in the module processes and transmits the processed voltage signal to a display device through communication, so that visual linear polarization information is obtained.
