Speckle patterns formed by broadband terahertz radiation and their applications for ghost imaging

Abstract Speckle patterns can be very promising for many applications due to their unique properties. This paper presents the possibility of numerically and experimentally formation speckle using broadband THz radiation. Strong dependence statistical parameters speckles, such as size sharpness on diffuser are demonstrated: correlation length mean square deviation phase surface inhomogeneity. As is increasing, also increases its goes down. Alternatively, magnification standard height leads diminishing growth sharpness. The dimensions formed speckles correspond results numerical simulation. utilizing implementation ghost imaging technique has been demonstrated by methods modeling.
