Abstract

The Manipulation of g^(2)(0) peak value of Hanbury Brown-Twiss (HBT) effect is discussed with a holographic projection scheme. By the aid of target pattern artificially designed in the projection imaging system, the statistical distribution of projection pattern will be highly controllable. In this work, we theoretically point out key factors influencing the g^(2)(0) peak value of HBT effect in a single-lens incoherent imaging system. We find the peak value is not only decided by statistical property and coherence length of target pattern but also depends on the intrinsic characteristics of projection system, such as numerical aperture and projection quality. Then, we experimentally measured the g^(2)(0) peak value of HBT effect with a phase-only holographic projection scheme and demonstrate the applicability of our theoretical analysis on the holographic scheme. Here, the super-bunching effect in the projection plane has been observed, when target patterns originated from chaotic speckle or it's function transformation patterns. Moreover, we design some sparse target patterns, whose holographic reconstruction patterns show the super-bunching effect achieving g^(2)(0)=39.77. Finally, we discussed the positive influence of holographic noise on increasing the g^(2)(0) peak value. The presented work predicting the peak value of HBT effect not only is applicable for the lens imaging system but also in other projection systems, such as the holographic projection.
