We introduce a class of twisted sinc-correlation partially coherent array sources, by applying the construction theory correlation function. Spectral density such novel focused beam propagating in free space is analyzed. It shown that intensity distribution presents good effect and splitting phenomenon upon propagation. The dimension, spatial lobes can be flexibly regulated altering source parameters. also explore evolution multiple singularities this light field, where phase appears as rotational spiral windmill profile during Furthermore, coherence orbital angular momentum investigated. These findings could useful particle manipulation free-space optical communication.
