Research on Intensity-Correlated Interferometry with Ultra-Weak Light Based on Coincidence Counting
Pulsar navigation requires the precise measurement of pulsars. Pulsar X-ray radiation has an extremely short coherence time, and satellite detectors receive only ultralow photon flux. Therefore, to obtain pulsar information and under the conditions of ultralow photon flux, intensity-correlated detection should be implemented. To solve this problem, we conducted an experimental study of intensity-correlated interferometry using a simulated visible-light source. We obtained second-order interference fringes and a corresponding angular diameter. We analyzed herein how coincidence counting affected measurement errors and how the spatial and temporal resolutions of the detecting system affected the intensity-correlated interferometry. The results provide a basis for determining the hardware parameters for X-ray intensity-correlated detection of pulsars.
