    Abstract

    The boiling phenomenon of the subjective laser speckle produced by a moving diffuser is applied for lens testing by two methods, in one of which the temporal auto-correlation of the fluctuating signal detected at a certain point in the speckle field is used for measuring the modulation transfer function (MTF) of the lens through which the speckle is produced. Using an automated MTF measuring system developed on this principle, some experimental results are obtained for an ordinary camera lens as well as a gradient-index (GRIN) rod lens. In the other method, the spatial cross-correlation of two speckle patterns produced before and after the diffuser translation is used for visualizing the non-uniformity of imaging capability of a GRIN rod-lens-array.
