基于全斯托克斯偏振超表面的透明物体应力检测装置及方法
By using a transparent object stress detection device based on a fully Stokes polarized metasurface, the device separates polarized light using a metasurface polarizer designed with matrix Fourier optics and calculates stress distribution using the phase-shifting method. This solves the problems of systematic error and poor dynamic response in existing methods and enables real-time online stress monitoring of transparent components.

AI Technical Summary
Existing methods for stress detection of transparent components are prone to introducing systematic errors, inaccurate measurement results, and poor dynamic response, making it difficult to achieve real-time online monitoring.
A stress detection device for transparent objects based on a fully Stokes-polarized metasurface is used, including a light source, a polarizer, a metasurface polarization analyzer, a detector, and a processing module. The metasurface polarization analyzer, designed with matrix Fourier optics, separates linearly polarized light into four diffracted beams with different polarization states, and the stress distribution is calculated by combining the phase shift method.
It enables full-field, real-time, and visualized imaging of stress in transparent objects, improving detection accuracy and speed, adapting to the trend of miniaturization and integration of optical platforms, and meeting the needs of online real-time monitoring.
