When laser light strikes a white wall or just some surface in space, a speckle pattern is observed. An example is given in Fig. 6.1. As a similar phenomenon is not observed with incandescent light or light from a spectral lamp, it must be a special property of laser light. Indeed, it is the special coherence properties of laser light that lead to the appearance of speckle patterns.
