Summary: This study presents a polarization interferometry-based technique for high-resolution and stable measurement of roll angular displacement. The technique uses a polarization camera to detect the phases of a light beam passed through a birefringent crystal and determines the angular displacement of the crystal based on variations in phase difference. The dual beam configuration of the proposed measurement scheme overcomes the effects of fluctuating incident angular displacement. Experimental results show that the system achieved a resolution of 0.58 arcsec within a 10-degree range and exhibited lower disturbance from incident angular displacement compared to previous techniques. The study also investigates nonlinear periodic system errors. The proposed technique offers higher resolution, wider range measurement capabilities, and robustness against external disturbance compared to existing methods.

Summary: This research paper focuses on the development of a digital holography system that can simultaneously measure deformations at dual spatial resolutions. The system uses two optical channels with different fields of view to achieve this. By introducing spatial carrier fringes with different orientations and utilizing polarization techniques, the two interferograms can be separated and analyzed to calculate the deformations. The experimental results confirm the practicality of this method.

Summary: In this article, we propose a protocol for nuclear spin polarization in a spin-star configuration, achieved through measurements. By optimizing a sequence of measurements with unequal time spacing, hundreds or even thousands of randomly aligned nuclear spins can be almost fully polarized. Compared to conventional methods, this protocol is not sensitive to magnetic field intensity and is robust against extra counterrotating interaction in the near-resonant situation.

Summary: The dynamics of damage inside fused silica induced by a femtosecond laser was studied using a single-pulse ultrafast measurement system. It was found that there is a quantitative relationship between the size of the damaged area and the pulse energy, and the structure inside the damaged area evolves before the formation of a double-void structure.

Summary: A single pulse diffraction method was proposed to probe the plasma column evolution induced by femtosecond laser pulses. The plasma rapidly expands within 7 ps due to ionization, reaching a steady state with a diameter of about 80 μm. The method allows for the determination of free electron density and refractive index in the plasma region using physical models.

Summary: This study introduces a novel approach using monoclonal antibodies as molecular probes to detect and monitor conformational changes of troponin subunits. The effectiveness of this approach in assessing ligand-induced conformations of troponin subunits in physiological conditions is demonstrated through a comparison of high-throughput microplate assay and localized surface plasmon resonance. This method requires small amounts of protein and is free of protein modification.

Summary: In this article, a method is proposed to directly measure underwater sound velocity using dual-comb lasers and matched filtering. The acousto-optic effect between the frequency comb and ultrasonic waves is applied to calibrate the time of flight (TOF). The dual-comb interferometry technique is utilized to determine the underwater sound velocity. Experimental results show that the method achieves a kilohertz-scale sound velocity measuring rate and has an uncertainty of better than 0.037 m/s for a single measurement. Moreover, compared with commercial sound velocity profilers (SVPs), the method exhibits a standard deviation of 0.0154 m/s during long-term measurements.

Summary: A dual cross-axis interference polarization-maintaining fiber interferometer (DCAI-PMFI) is proposed for simultaneous measurement of strain and temperature. The sensitivity matrix for simultaneous measurement of temperature and strain is constructed, and the decoupling performance of the two parameters can be optimized by adjusting the length ratio of two arms. Experimental results demonstrate that the proposed sensor can effectively mitigate the crosstalk between strain and temperature, making it suitable for various interferometric fiber sensors.
