AI Technical Summary
Existing technologies struggle to achieve dynamic imaging detection of the optical anisotropy of polymer orientation functional materials, especially in cases of thick or strongly absorbing samples. Furthermore, traditional methods are limited by imaging depth and transparency, making it impossible to accurately characterize the effect of temperature on optical anisotropy.
Polarized photoacoustic imaging technology is used to control the laser source module to emit pulsed lasers, which are combined with a water bath constant temperature module to heat the sample. Photoacoustic signals under different temperature gradients are collected, optical anisotropy is calculated, and two-dimensional scanning imaging is performed to obtain the glass transition temperature and temperature dependence coefficient of the material.
It enables dynamic imaging of the optical anisotropy of polymer-oriented functional materials, overcomes the limitations of thickness and transparency, provides high-resolution and deep-penetration optical imaging, and can monitor the effect of temperature on the optical anisotropy of materials in real time.
