A new stereo-photolithography technique to create three-dimensional micro-components using a planar, layer-by-layer, process of exposure has been developed. With this procedure, it is possible to build components with dimensions in the range 50 μm

Two epoxy resins are investigated using non-degenerate four-wave mixing. The materials assessed are optimised for use with a UV argon-ion laser. The holographic gratings were written at a wavelength of λ = 351.1 nm for an irradiance range 0.5-3.0 W/

We report the development of a new microstereophotolithography technique for creation of three-dimensional microcomponents by use of a planar, layer-by-layer process of exposure, in which a spatial light modulator is used as a dynamic lithographic ma

We present the implementation of a clutter-tolerant filter in a hybrid correlator system. Wiener filters were mapped with a complex encoding technique onto a smectic A(*) liquid-crystal spatial light modulator (SLM). The technique overcomes the probl

Counterfeiting is now a global problem. Seven percent (7%) of all world trade is in counterfeit goods. Counterfeit goods do not only target famous brand names but anything that can buy. Virtually every country in the world suffers from counterfeiting

A technique for the experimental implementation of fully complex filters with commercially available spatial light modulators (SLMs) is reported. The filters are incorporated into an all-optical correlator and a hybrid digital-optical correlator, the
