Nineteen Ways to do 3-Dimensional Imaging
... Speckle interferometry is also known as electronic speckle pattern interferometry or as TV holography. It depends on the object being imaged to have a diffusely reflecting (i.e., rough) surface to create the speckle pattern. It also requires a reference surface which must also be diffusely reflectin ...

... Simple optical surfaces reflect a portion of the light. This can be a problem because not only is the desired light reduced, but also the reflected light is not lost, but just goes somewhere else. Somewhere else can often be the image plane, where it causes ghost images and veiling glare. Most s ...
