1. A method of distorting the temporal and spatial phase of a light beam, comprising the steps of:

  • a) providing an electro-optic device having, i) an electro-optic substrate, ii) an electrode array arranged on the surface of the electro-optic substrate, iii) at least one electrode located on the opposite surface of the electro-optic substrate, and iv) means for applying voltage to the electrodes to generate a variation in a refractive index profile within the substrate; and

    b) directing the light beam through the electro-optic device while applying voltage to the device, whereby the temporal and spatial phase are altered, thereby reducing the appearance of speckle.
