Abstract
Detailed description is given of a holographic coding plate that encodes position coordinates of quantized spatial regions on the coding plate. A coding plate fabrication method is described that makes it possible to produce a coding plate of 2(m) x 2(n) quantized regions by a total of (m + n) exposures. Reconstruction of point images and their immobility are discussed in a framework of the first-order approximation. Dancings of the reconstructed point images are explained in terms of the third-order aberrations. Intensity variations of the reconstructed point images due to the volume holographic effect are discussed. Outline of a holographic graphic input device called a Holotablet, which is an example of the application of the holographic coding plate, is described.
