Monte Carlo simulation for speckle reduction using moving diffuser

Abstract

We have been working on speckle phenomena, in measurement and reduction, because it is very hazardous in laser projection displays. [1-4]. So far numerical simulation for speckle given in the literature has been limited to speckle formation. [5] More recently numeral simulation for speckle reduction is discussed in terms of the point spread functions, which stand the correlation cell and the resolution cell for the projection and viewing systems, respectively. [6, 7] We will report Monte Carlo simulation for speckle reduction on images, which are formed by a number of point spread functions, where novel ideas in image processing such as image interpolation by zero padding in its frequency domain are introduced.
