提出了一种基于光折变晶体中空间调制不稳定性的近红外图像重建方法。根据调制不稳定性增益理论，讨论了近红外调制不稳定性形成的条件。在1064 nm波长下的散射图像重建实验结果表明，最大互相关系数和互相关增益分别为0.57和2.09。该方法有望成为近红外成像技术的辅助手段。
We present a method of near-infrared image reconstruction based on spatial modulation instability in a photorefractive strontium barium niobate crystal. The conditions that lead to the formation of modulation instability at near-infrared are discussed depending on the theory of modulation instability gain. Experimental results of scattered image reconstruction at the 1064 nm wavelength show the maximum cross-correlation coefficient and cross-correlation gain are 0.57 and 2.09 respectively. This method is expected to be an aid for near-infrared imaging technologies.
