ABSTRACT
But this changes if you can persuade the subject to move into the plane of the hologram. The ‘focal length’ of the hologram (considered as an optical component) becomes zero, and the temporal and spatial coherence of the replay source become irrelevant. There are two ways of achieving this: you can use the pseudoscopic image generated by flipping a first-generation transmission hologram, or the optical image produced by a lens. It is the former stratagem that is dealt with in this chapter; the latter is the subject of Chapter 14.
