Abstract
One characteristic of conventional holograms is that they13; require coherent light source for reconstruction and the images thus retrieved are of single colour. In contrast, white light holograms when viewed against an inexpensive ordinary white light source reconstruct images in multicolours. The objective of the present report is13; (a) holographic techniques due to Benton, Yu et a1 and13; to briefly review the origin and development of white light13; (b) to describe independent observations made by the present authors in constructing white light holograms in a single step and using the technique for recording vibrations patterns of mechanical components.
