摘要： A process and an apparatus for measuring the biocurrent distribution call for initially assuming a number of multiple currents which is more than the number of isolated currents possibly existing in a living body and calculating the virtual magnetic field created by the assumed currents at actual measuring points. The estimated location and current vectors of said assumed currents are consecutively changed to decrease the difference between said virtual and actual magnetic fields so that the estimated location and current vectors of the assumed currents having the number corresponding to the true isolated currents substantially approximate the true values and the estimates of the other assumed currents approximate zero. This enables the biocurrent distribution to be exactly determined even when the number of isolated currents is not preliminarily known.

摘要： The present invention provides a method and apparatus for producing a hologram from a series of two-dimensional images horizontally different in line of sight from each other. The holographic apparatus employs original images produced by photographing an object from different directions, an object optical system which makes a light be incident upon original image to project an object beam onto photo-sensitive material, and a reference optical system which projects a reference beam of a same wavelength as the object beam toward the photo-sensitive material. The horizontal component of the object beam can be converged at a rear point i.e., a point of view at image reproduction, relatively distant from the photo-sensitive material on which a hologram is produced. When the hologram is reconstructed, a beam having the same wavelength as when recorded is converged at the rear point of view, so that the reconstructed image can be viewed in a same color free from any color shading.
