摘要
Transverse modulation instability (MI) has been proved useful for reconstructing noisy images. However, the signal-noise resonances for high-frequency modes are always suppressed during the generation of instability, resulting in the blurring of output images. By controlling of photo-birefringence and isomerization of azobenzene-derivative polymer, we proposed an instability-driven reconstruction by re-growing high-frequency modes via localizing wave response. The agreement between the experimental results and numerical simulations proves its effectiveness. This work provides a general and flexible way for high-resolution target detection.
