Abstract
In this chapter, we will discuss the basic physical origins of speckle and present different, but related, mathematical descriptions of speckle in simple model systems. We will start from a general description of scattered waves as phasors, deriving first-order statistics applicable to both laser speckle and ultrasound speckle. Subsequently, we discuss the correspondences and differences between laser speckle and ultrasound speckle, before presenting higher order statistics and imaging implications in an ultrasound context. We also introduce the impact of the imaging system characteristics on speckle appearance and statistics.
