论文摘要
夜视是在弱光条件下看到的能力。但是，传统的夜视成像技术受到必要的高性能红外焦平面阵列的限制。在本文中，我们提出了一种新颖的色彩夜视成像方案，而无需使用红外焦平面阵列。在实验设备中，目标反射的两波长红外激光束由空间灯调节器调节，并通过光电倍增管管检测到输出灯。通过测量两个光场之间的二阶强度相关函数来重建两个红外夜视图像。因此，传统夜视成像中光电检测的处理模式转化为光场控制的处理模式。此外，处理两个具有不同光谱的灰色图像以形成彩色夜视图像。我们表明，可以通过这种方法获得高质量的色彩夜视图像。
Night vision is the ability to see in low-light conditions. However, conventional night vision imaging technology is limited by the requisite high-performance infrared focal plane array. In this article, we propose a novel scheme of color night vision imaging without the use of an infrared focal plane array. In the experimental device, the two-wavelength infrared laser beam reflected by the target is modulated by a spatial light modulator, and the output light is detected by a photomultiplier tube. Two infrared night vision images are reconstructed by measuring the second-order intensity correlation function between two light fields. Thus, the processing mode of optical electric detection in conventional night vision imaging is transformed into the processing mode of light field control. Furthermore, two gray images with different spectra are processed to form a color night vision image. We show that a high-quality color night vision image can be obtained by this method.
