Abstract

In this chapter we explore some interesting properties of speckle behavior in the vicinity of the locations where speckle intensity vanishes (i.e., near the zeros of speckle intensity). To do so, we first generate a speckle pattern from a simple simulated uniform diffuse object. We then find the real and imaginary parts of the speckle field and find where each of them simultaneously is zero. At such points the intensity is also zero. We then explore the structure of the speckle phase in regions close to and surrounding these zeros of intensity.
