The recent investigations on quantum effects in nonlinear optical patterns and spatial aspect of squeezing have focused on the concept of quantum image [1,2,3]. These are very noisy images images, dominated by quantum fluctuations and can be revealed either 1) by high frequency observation, which is able to reveal the fast dynamics of fluctuations, or 2) by low frequency observation, by measuring the spatial correlation function. This displays a regular modulation, which anticipates the stripe pattern that appear above threshold [4], while the intensity distribution is uniform on average.
