(A) Four frames with single or pair of photons circled by blue circle indicating the identification of the positions of photons. A white arrow points to the locations of the photons. The red circle in the first frame panel indicates the center of the SPDC illuminating cone (Bragg spot). (B) An image generated by accumulating all the photons though out the simulation. The red circle in the center indicates the center of the SPDC illuminating cone as identified using the watershed algorithm from Sect. 4.2.1. (C) An image of several frames integrated on the detector. The red circles indicate the position of the photons, and the green line connects a pair of biphotons indicated using the algorithm in Sect. 4.2.3.
