a reproduction of a light field produced by a scene

In some embodiments of the invention, a hologram is a reproduction of a light field produced by a scene.

a three-dimensional image made with the aid of a laser

As stated, a hologram is a three-dimensional image made with the aid of a laser.

a structure which diffracts the light on an image

A hologram is actually a structure which diffracts the light on an image. '

a three-dimensional image reproduced from a pattern of interference

A Hologram is “a three-dimensional image reproduced from a pattern of interference” (click here for images and more info).

a capture of the light field at a particular moment in time and space

A hologram is in essence a capture of the light field at a particular moment in time and space.

three-dimensional images

Holography is a technique which enables three-dimensional images (holograms) to be made.

a recording of an interference pattern between two beams of light

A hologram is a recording of an interference pattern between two beams of light, so that illumination with one beam automatically reconstructs the other, creating a 'three-dimensional' image.

a “real-world recording of an interference pattern which uses diffraction to reproduce a 3D light field

A hologram is a “real-world recording of an interference pattern which uses diffraction to reproduce a 3D light field, resulting in an image which still has the depth, parallax, and other properties of the original scene”.

a three-dimensional image, created with photographic projection

By definition, a hologram is a three-dimensional image, created with photographic projection.

a three-dimensional image confined in two dimensions

A hologram is a three-dimensional image confined in two dimensions.

a photographic recording of a three-dimensional image

A hologram is, in short, a photographic recording of a three-dimensional image.

a three-dimensional image of an object, which is produced by recording on photographic film the interference patterns formed by a split laser beam

As you know, a hologram is a three-dimensional image of an object, which is produced by recording on photographic film the interference patterns formed by a split laser beam.

a specially constructed image which, when illuminated by a laser beam, seems eerily suspended in three-dimensional space

A hologram is a specially constructed image which, when illuminated by a laser beam, seems eerily suspended in three-dimensional space.

In essence

A hologram is in essence a capture of the light field at a particular moment in time and space.

that allows an image to be recorded in three dimensions

A hologram is an advanced form of photography that allows an image to be recorded in three dimensions.

a permanent record of what something looks like seen from any angle

So a hologram is effectively a permanent record of what something looks like seen from any angle.

the photographic record of the spatial interference pattern created by the mixing of two coherent laser beams

In its basic form, a hologram is the photographic record of the spatial interference pattern created by the mixing of two coherent laser beams.

a 3D photograph of a person that, when lit properly, captures the person’s physical presence

A hologram is a 3D photograph of a person that, when lit properly, captures the person’s physical presence.

a flat, two-dimensional film with which light can be made to interact to project a three-dimensional image

In our physical world, a hologram is a flat, two-dimensional film with which light can be made to interact to project a three-dimensional image.

an incorrect household name for an image, covered on top with a microprism grating, due to which

A hologram is an incorrect household name for an image, covered on top with a microprism grating, due to which a purely mechanical separation of the image takes place - the left eye sees one half simply because the image looks to the left, the right eye - similarly.
