Latest Patents

Stephen holds a patent for a "Multi-spectral holographic security marker, method for its manufacture and holographic security system." This invention involves a novel method that utilizes a replay frequency shift to achieve one or more final replay frequencies of specific parts of a recorded image plane volume hologram. The security marker consists of an optional surface hologram and an image plane volume hologram, which is divided into discrete areas with different final replay frequencies. The security information is conveyed through the size and shape of these areas, along with the hologram content itself. This innovative approach includes the possibility of having one volume hologram replay frequency in the visible spectrum and another in the invisible part of the spectrum, such as infrared or ultraviolet.
