Array generation with lenslet arrays.
Lenslet arrays can be used as phase gratings, having many diffraction orders with equal intensity. Applications are multiple imaging and illumination of arrays of optical or optoelectronic devices in digital optics. The homogeneity of the intensities within the array can be improved by using field lenslets. The basic theory as well as experiments with diffractive and with graded index lenses are shown.
