AI Technical Summary
Existing optical measurement methods struggle to capture the nanosecond to millisecond-level dynamic modulation effects caused by the motion of microscopic particles, and are also unable to achieve effective separation of the spectral, polarization, and temporal dimensions in single-point detection, resulting in multidimensional information aliasing, low signal-to-noise ratio, and incomplete dynamic feature extraction.
A modulated composite probe optical field is constructed, which includes an optical field with multiple independent intensity modulation frequencies and a unified polarization state scanning frequency. The modulation frequency is set by the frequency domain layer isolation principle. The frequency domain decoupling processing and time domain correlation analysis are performed using a single-channel time-series response signal to generate a dynamic response fingerprint.
It achieves single-point detection of high-dimensional light field information, solves the problems of high hardware cost, complex optical path alignment and difficulty in decoupling in traditional methods, improves the signal-to-noise ratio and accurately extracts dynamic optical fingerprints.
