lnslt_arr_transform - filters the field through lenslet array.
propagation the field to the far field of the lenslet array. This propagation is effected using the Goertzel-Reinsch algorithm, and wavefront pixels that straddle boundaries are properly weighted. By default the propagation leaves the wavefront in the focal plane of the lenslet array, with Nyquist sampling.
