Since the celebrated twist phase was proposed by Simon and Mukunda, despite tremendous progress made in theory over past decades, developing a simple flexible experimental method to customize this novel has long been tricky challenge. In Letter, we demonstrate general for generating twisted Schell-model beams implementing continuous coherent beam integral function discrete form. Experimental results based on rigorous Laguerre–Gauss modes superposition are also demonstrated, indicating that our is more convenient of higher quality. The factor measured using rotation characteristics during propagation, agree well with theoretical prediction. could serve as way customizing bona fide cross-spectral densities while facilitating certain applications.
