Paper Abstract

Fluctuations, under common conditions regarded as noise or clutter, often are carriers of very useful information. This information may be turned into usable form if the degree of distinctions between fluctuating signals can be determined. To visualize statistical parameters of two-dimensional fields of fluctuations, these parameters are proposed to be converted into videosignals, forming conventional TV image. Recursive technique is applied to such parameter as variance, modified into temporal contrast. Description of visualizer configuration is preceded by a summary of background for speckle-originated fluctuations in turbulent atmosphere when retroreflected from diffuse and mirror surfaces. The possibilities are discussed for controlled speckle displacements using laser beam scanning or phase/frequency swip.
