提出了一种基于光折变半导体CdZnTe:V调制不稳定性的近红外图像恢复方法。讨论了CdZnTe:V中调制不稳定性的形成机理，推导了理论增益模型。在1µm和1.5µm波长下的光学图像恢复理论结果表明，最大互相关增益为2.6，信噪比为0.1。这些结果表明，我们的方法可能是近红外成像的潜在辅助手段之一。
We propose a near-infrared image recovery method based on modulation instability in the photorefractive semiconductor CdZnTe:V. The formation mechanism of modulation instability in CdZnTe:V is discussed, and the theoretical gain model is derived. Theoretical results of optical image recovery at 1 µm and 1.5 µm wavelengths demonstrate that the maximum cross-correlation gain is 2.6 with a signal to noise intensity ratio of 0.1. These results suggest that our method could be one of potential aids for near-infrared imaging.
