  text: We have detected a spin-dependent displacement perpendicular to the refractive
    index gradient for photons passing through an air-glass interface. The effect
    is the photonic version of the spin Hall effect in electronic systems, indicating
    the universality of the effect for particles of different nature. Treating the
    effect as a weak measurement of the spin projection of the photons, we used a
    preselection and postselection technique on the spin state to enhance the original
    displacement by nearly four orders of magnitude, attaining sensitivity to displacements
    of ∼1 angstrom. The spin Hall effect can be used for manipulating photonic angular
    momentum states, and the measurement technique holds promise for precision metrology.
