Baolei Liu, Fan Wang, Chaohao Chen, Fei Dong, David McGloin

摘要:

重影成像可以用点探测器而不是阵列传感器来捕获2D图像。因此,它提供了一个解决方案,以挑战建筑面积格式传感器的波段,这种传感器是困难和昂贵的生产,并开辟了新的成像模式,由于高性能的单像素探测器。传统上,重影成像通过将测量的光强度与应用的照明图案相关联来离线检索对象的图像。在这里,我们提出了一种基于反馈的方法,在线更新的成像结果,可以绕过后处理,称为自进化鬼成像(SEGI)。我们引入了遗传算法来优化照明模式,实时匹配的物体形状,根据测量的总光强度。我们从理论和实验上证明了这个概念的静态和动态成像。该方法为遥感(例如机器视觉、自动驾驶车辆中的激光雷达系统)和生物成像等应用中的实时重影成像开辟了新的前景。

英文摘要:

Ghost imaging can capture 2D images with a point detector instead of an array sensor. It therefore offers a solution to the challenge of building area format sensors in wavebands where such sensors are difficult and expensive to produce and opens up new imaging modalities due to high-performance single-pixel detectors. Traditionally, ghost imaging retrieves the image of an object offline, by correlating measured light intensities and applied illuminating patterns. Here we present a feedback-based approach for online updating of the imaging result that can bypass post-processing, termed self-evolving ghost imaging (SEGI). We introduce a genetic algorithm to optimize the illumination patterns in real-time to match the objects shape according to the measured total light intensity. We theoretically and experimentally demonstrate this concept for static and dynamic imaging. This method opens new perspectives for real-time ghost imaging in applications such as remote sensing (e.g. machine vision, LiDAR systems in autonomous vehicles) and biological imaging.
