We show that quantum detection of the radiation field yields a linear diffraction pattern that reveals $\\sigma(\\mathbf{q})$ itself, including the phase. We further show that repeated diffraction measurements with variable delays constitute a novel multidimensional measure of spontaneous charge-density fluctuations.
