[IP4-02] Vortices in two-point correlation function

*Akanksha Gautam1, Rakesh Kumar Singh1 (1. Indian Institute of Technology, BHU, Varanasi)

We present a method to generate a helical phase structure in two-point correlation function using the polarization basis of light. The method is based on the van Cittert–Zernike theorem, establishing a connection between an incoherent source and the two-point correlation function in the far-field. Experimental measurement of the helical phase in the two-point complex correlation function is carried out by a radial shearing interferometer.
