摘要： A projection system that facilitates the use of in-situ detection of a change in wavelength, thereby enabling appropriate compensation or corrections to be applied on the fly to improve the quality of the image in the primary image region. In-situ detection in this manner can allow wavelength changes due to both temperature fluctuations and hardware variations to be compensated for simultaneously, thereby reducing the time and expense for end of line hardware testing, and removing the need to perform in-situ mapping of the wavelength as a function of temperature. In this way, the quality of the image provided to a user can be improved in a simpler, more efficient manner.

摘要： Holographic stereograms and holographic optical elements are printed using computer rendered images of 3D computer models or processed images. Printing of one-step, full-color, full-parallax holographic stereograms uses a reference beam-steering system to expose a holographic recording material from different angles by a reference beam. A coherent beam is split into object and reference beams that interfere with each other at an elemental hologram on a holographic recording material. A voxel-control lens can be placed in the path of the object beam and in close proximity to the holographic recording material to control resolution of a holographic stereogram. Interchangable band-limited diffusers and reference-beam masking plates, and viewing zone techniques can be used in the rendering process.
