The focus of this presentation is to highlight the different ways in which artists and scientist create depth within their holograms and will explore three main examples of how this can be done. The first is using mirrors to create depth in holograms this is a very technical method which requires allot of aligning as interference can occur when using mirrors in holograms. The element of depth is achieved using a method of controlling the point at which the object beam intersects the reference beam, this is similar to the double beam. The double beam holography method, uses a reference beam and an object beam which allows for the creation of more depth within holographic spaces by adjusting the position of where the object and reference beam intersect, leading to a deeper positioned image. A simpler approach can however, if fined tuned, can give good results, simply by moving the plate further away from the object being recorded, can give the illusion of the object appearing deep in the holographic space. Finally, and by far the most astonishing way of creating holographic space is by selecting the appropriate object, sometimes the wonder of holographic recording itself can be enough to demonstrate this principle using a long object such as a pitch fork, as seen in the image below can be enough to create a deep image.
