Spatially integrated speckle intensity: maximum resistance to decorrelation caused by in-plane target displacement
Laser speckle produced from a diffuse object can be used in determining the angular position of a rotating object. When the object rotates the backscattered speckle pattern, which changes continuously but repeats exactly with every revolution, is sampled by a suitably positioned photodetector. The p...
