    摘要: This invention relates to holographic image display systems, and to related methods and processor control code. We describe a method of displaying an image holographically, the method including: inputting display image data defining said image for display; processing said image data to determine first image data representing a first spatial frequency portion of said image data and second image data representing a second spatial frequency portion of said image data, wherein said second spatial frequency is higher than said first spatial frequency; displaying a hologram of said first image data on a spatial light modulator (SLM) to form a holographically-generated intermediate real image; modulating said intermediate real image using said second image data to display said image.

    摘要: The invention relates to a computer-generated hologram fabrication process that can reduce loads on computation of interference fringes for an original image including micro-characters. A visually perceivable original image 11 and a visually unperceivable original image 12 (micro-characters) are defined, and sample point sources of light P are defined at a low density on the original image 11 and at a high density on the original image 12. Interference fringes of object light coming from the point light sources on the original image 11 and reference light R are found on each computation point within an area α1 on a recording surface 20, and interference fringes of object light coming from point light sources on the original image 12 and reference light R are found on each computation point within an area α2 on the recording surface 20. The light sources that become samples are defined at a given pitch on sectional lines obtained by cutting the original images 11 and 12 by a multiplicity of sections (parallel with an XZ plane) located at a given spacing. The section-to-section spacing for the original image 12 is made narrows than that for the original image 11.
