  • SYSTEM AND METHOD FOR VISUAL QUALITY CHARACTERIZATION OF HOLOGRAPHIC MATERIALS
    Publication number: 20090097034
    Abstract: Apparatus and method for characterizing perceived visual quality of holographic materials, such as diffraction gratings. A white light source directs a collimated beam onto an embossed material. The first order diffracted light strikes a white background directly in view of a digital camera, which records an image. The image is analyzed to calculate total color intensity of the diffracted light and an estimate of the color distinctness. The data is compared to other samples to determine relative visual quality.
