摘要： The invention provides in particular for an achromatic diffractive diffuser comprising a surface relief diffractive device arranged such that, under illumination by ambient light, the diffractive effect serves to provide a uniform achromatic diffuser reflection into a defined viewing zone for observation by an observer, and also such that the achromatic diffractive replay of the device has a non-symmetric distribution of diffractive light intensity between positive and negative diffractive order such that the diffractive efficiency in the desired diffractive order is enhanced over that of the undesired order to provide an enhanced brightness achromatic device.

摘要： An optical device for security and anti-counterfeit applications comprises a diffractive structure comprising a discrete region that in response to white light illumination generates an image by a process of diffraction in close angular proximity to the specular reflection and which is thus substantially non-visible to an observer, and which under coherent illumination generates a laser projection covert image which forms an image in an image plane located away from the physical plane of the device and which is angularly co-located in close proximity to the direction and position of the specular reflection.

摘要： The present invention provides for a tamper resistant data protection security laminate structure in the form of a holographic and/or diffractive security laminate, wherein the laminate base film consists of a relatively thin base film of a fragile, frangible material, characterised by having a low internal strength and a tendency to tear or distort under heat or mechanical attack to provide visible damage and destruction of the holographic image and data protection laminate, and wherein the laminate carries a holographic and / or diffractive security image visible for authentication to an observer under normal lighting conditions and wherein remainder of the film is made up of a relatively thick layer of a suitable hard permanent adhesive which under normal room temperature is a solid material characterised such that under high temperature heat attack the permanent adhesive eventually softens and melts but the frangible base material at this point has insufficient internal strength to be self supporting and is visibly damaged upon attempted removal and wherein the thickness of frangible base film lies within the range of 5% to 60% as a proportion of the total laminate thickness.
