Abstract

Speckles can be classified as -- laser generated virtual speckles and artifically generated real speckle. An additional type termed Sampled Speckles has arisen due to the discrete nature of digital recording. Alternatively speckles are classed as -- objective speckles which are limited by the resolution of the recording medium and subjective speckles which depend on the cut-off frequency of the recording lens. Sampled speckles are limited by the sampling frequency of digital recorders. The generation of these speckles and their applications will be discussed in this paper.
