Abstract
In [Appl. Opt. 56, 7079 (2017) [CrossRef] ], an attractive phase unwrapping algorithm based on the transport of intensity equation is proposed. Although the effectiveness is experimentally evaluated, the derivation of the angular spectrum based expression is ambiguous. In this paper, the ambiguity is clarified with the Helmholtz equation.
