Abstract

Be it quantum or classical, optical field is intrinsically of stochastic nature, and is generally composed of predictable and unpredictable components. It seems to be a common belief that the deterministic component of the optical field serves as a useful signal while its random component acts as a disturbing noise. Such a common belief based on the simple “good and evil dualism” does not hold for optical speckle fields, which have much subtler characteristics. While speckles are already known to be useful in optical metrology, they are still considered as a nuisance in imaging. This talk will introduce a methodology and techniques that illustrate how the speckles can be turned from a harmful noise to a useful vehicle for imaging.
