The data defining an object to be holographically reconstructed is first arranged into a number of virtual section layers, each layer defining a two-dimensional object data sets, such that a video hologram data set can be calculated from some or all of these two-dimensional object data sets. The first step is to transform each two-dimensional object data set to a two-dimensional wave field distribution. This wave field distribution is calculated for a virtual observer window in a reference layer at a finite distance from the video hologram layer. Next, the calculated two-dimensional wave field distributions for the virtual observer window, for all two-dimensional object data sets of section layers, are added to define an aggregated observer window data set. Then, the aggregated observer window data set is transformed from the reference layer to the video hologram layer, to generate the video hologram data set for the computer-generated video hologram.

Disclosed is a periscopic device for examining an eye of a person with an inwardly squinting eye (esotropia). The periscopic device includes a tube with two mirrors arranged at opposite ends of the tube. The mirrors are arranged so that when the person looks through the periscopic device with the inwardly squinting eye, the two mirrors deflect the line of sight of the person toward an object reflected in the second mirror. To account for the squint of the eye, either a base out prism can be used to deflect the line of sight toward the first mirror, or the two mirrors can be arranged non-parallel to each other. With the inwardly squinting eye focused on the reflected object, the other eye can be examined. Methods of using the periscopic device are also disclosed.
