1. A non-transitory storage medium storing thereon an optical aberration correction program, the optical aberration correction program causes, when executed by a computer with a processor, the computer to perform:
obtaining, by the processor, phases of a plurality of provisional optical transfer functions of an optical system corresponding to a plurality of provisional optical aberration amounts of the optical system, the optical system including a lens;
generating, by the processor, a plurality of three-dimensional phase-modulated images by deconvolving a three-dimensional original image of a sample with each of the phases of the plurality of provisional optical transfer functions, the three-dimensional original image of the sample obtained by an optical apparatus including the optical system and an imaging device and including an optical aberration of the optical system;
obtaining, by the processor, an optimal theoretical three-dimensional point spread function of the optical system corresponding to a three-dimensional phase-modulated image whose index of luminance value is maximum among the plurality of three-dimensional phase-modulated images;
determining, by the processor, an optical transfer function of the optical system corresponding to the optimal theoretical three-dimensional point spread function;
generating, by the processor, a three-dimensional correction image by deconvolving the three-dimensional original image or another three-dimensional original image that includes the optical aberration of the optical system and is different from the three-dimensional original image with the optical transfer function; and
sending the three-dimensional correction image for display or for storing the three-dimensional correction image.
