  • Publication number: 20250110040
    Abstract: An image processing device illuminates light from a light source through an optical system with a first numerical aperture onto an examined eye, transmits signal light returning from the examined eye through an optical system with a second numerical aperture, and divides a reference light from the light from the light source. The image processing device detects interference light between the signal light and the reference light, and acquires information representing the obtained interference light. The image processing device performs a first process of projecting the information representing the interference light onto a four-dimensional frequency aperture formed by the optical system with the first numerical aperture and the optical system with the second numerical aperture, in a four-dimensional space of frequencies of the light source and frequencies of light from the examined eye according to the signal light, and a second process of projecting the projected information into three-dimensional space.
