A pair of combined diffractive optical elements (DOEs) realizes a so-called moiré lens, with an optical power which can be tuned by a mutual rotation of the two DOEs around their central optical axis. Earlier demonstrated moiré lenses still suffere

In a recent publication [Appl. Opt. 57, 8087 (2018).] a zoom system based on rotating toroidal lenses had been theoretically suggested. Here we demonstrate two different experimental realizations of such a system. The first consists of a set of four

We experimentally demonstrate a compact, on-axis device for two-dimensional steering of the direction of a transmitted beam. It consists of two adjacent diffractive optical elements (DOEs) corresponding to two decentered Fresnel lenses with opposite
