在计算机模拟和实验室演示中，我们使用强度干涉法对一组点源进行成像。我们通过使用三个单光子探测器测量光子到达时间之间的二阶和三阶相关性，获得了这个“星团”的图像。为了减少噪声的影响，我们将光集热器分成几个部分，每个部分分散到光谱带中，每个波段中的光子单独相关。这包括一种新的光学设计，它(1)对于部分准直的光束是稳定的，(2)是光效的，(3)不比入射光束宽。
We use intensity interferometry to image a group of point sources in a computer simulation and laboratory demonstration. We acquire the image of this “asterism” by measuring the second- and third-order correlations between photon arrival times using three single photon detectors. To reduce noise effects, we divide the light collector into segments, and each segment is dispersed into spectral bands, where photons in each band are correlated separately. This comprises a new optical design that (1) is stable for partially collimated beams, (2) is light efficient, and (3) is not any wider than the incoming beam.
