TLDR
In this article, an off-axis optical hologram is constructed of an object with an object modified light being passed through an array of small lenses or some other light modulator.Abstract:
An off-axis optical hologram is constructed of an object with an object modified light being passed through an array of small lenses or some other light modulator. Upon reconstruction of the hologram, a diffracted wavefront is passed back through the array of small lenses or other light modulator. Additionally, during reconstruction, a separate light diffusing element is placed in the path of the diffracted image-carrying beam prior to its striking the light modulator.read more

Method and apparatus for forming a hologram from incoherent light
TL;DR: In this article, a system for creating a hologram from a sequential series of two-dimensional transparencies is presented, where a camera in incoherent light and a projection apparatus using coherent light are combined to form a rainbow hologram of the scene originally photographed.

System and apparatus for the recording and projection of images in substantially 3-dimensional format
TL;DR: In this article, a system for the production of a second threedimensional image magnified from a first three-dimensional image in substantially the same proportions, including a first active optical system for creating from the 3D image, a first two-dimensional array, is described.

Speckle suppression of holographic microscopy
TL;DR: In this paper, a finely-structured and transparent light diffuser is interposed through the aerial image formed by a hologram or an image formed or relayed by a lens system such as a microscope objective prior to the eyepiece.

Holographic imaging using a lenticular screen
TL;DR: In this paper, a holographic image is produced by placing a lenticular screen between a coherant light source and a recording medium during creation of the image, which can only be observed if viewed through an identical LSH, but when so observed is clearer in poor lighting conditions than a conventional HMD.
