Abstract
Systems and methods can be configured to perform operations related to determining a phase transfer function of a digital imaging system. A digital image that includes at least one edge is received, the at least one edge includes a plurality of pixels with disparate pixel values. The at least one edge from the digital image is identified and an edge spread function is generated based on the identified edge. The edge spread function can be generated by taking at least one slice across the identified at least one edge. A line spread function is generated based on the edge spread function. An optical transfer function is generated based on a Fourier transform of the line spread function. A phase error is also identified. The phase transfer function of the digital image is identified based on the phase of the generated optical transfer function and the identified phase error.
