Experimental images of a single star and a binary star obtained with the THT test bench in the photon-counting regime. Two photon flux are investigated (top: 500 and bottom: 200 photons/frame). The number of pixels is equal to 50 across the clean field of view. These images are obtained by stacking 30 000 and 20 000 short-exposure images for 200 and 500 ph/fr respectively. The intensity ratio between the two components of the unbalanced binary star is set to 1:1000 and their angular separation is 25 μrad. The dynamic range (DR) of each long-exposure PSF measured before the background bias subtraction are close to 450 and 730 for 200 and 500 ph/fr, respectively.
