在这项工作中,我们解决了空间图案的重建,编码在光场与一系列的光脉冲发射的激光源和使用光子计数相机成像,与固有的响应显着长于脉冲延迟。采用贝叶斯方法,我们提出并实验证明了一种新的联合时间反卷积算法,利用这一事实,即单脉冲同时观察到不同的像素。使用一个1000 ps的门,步进10 ps的增量,加强CCD相机,我们展示了解决的能力,由10 ps的延迟,四倍更好地分离的图像相比,标准的反卷积技术。
In this work, we address the reconstruction of spatial patterns that are encoded in light fields associated with a series of light pulses emitted by a laser source and imaged using photon-counting cameras, with an intrinsic response significantly longer than the pulse delay. Adopting a Bayesian approach, we propose and demonstrate experimentally a novel joint temporal deconvolution algorithm taking advantage of the fact that single pulses are observed simultaneously by different pixels. Using an intensified CCD camera with a 1000-ps gate, stepped with 10-ps increments, we show the ability to resolve images that are separated by a 10-ps delay, four time better compared to standard deconvolution techniques.
