Fourier incoherent single-channel holography can record spatially incoherent digital holograms, avoiding the twin-image problem. This could enable the development of instruments such as holographic telescopes and video cameras.
A simple method for reconstructing digital color holograms, based on stretching techniques, yields good-quality synthetic holograms in which the constituent colors are multiplexed.
Mismatches between the point at which the eyes must converge and the distance to which they must focus when viewing stereoscopic images have negative consequences.
