Pseudo-thermal light imaging setup. A monochromatic laser is focused onto a rotating ground glass disk (RGGD) by means of lens L1. The subsequent lens L2 provides the far-field speckle pattern at the object plane (OP). The resolution of the single-lens (L3) imaging system can be modified by a variable-size pinhole (PH). Single photons are detected at the image plane (IP) by SuperEllen
