Abstract: An ophthalmologic information processing apparatus according to the embodiments includes a search unit, a correction unit, and a display control unit. The search unit is configured to search for filter information for correcting an aberration in complex OCT data of a subject's eye so that a quality of the complex OCT data becomes a predetermined level. The correction unit is configured to correct the aberration in the complex OCT data based on the filter information searched by the search unit. The display control unit is configured to display, on a display means, aberration information on a pupil surface of the subject's eye corresponding to the filter information searched by the search unit.

Abstract: An ophthalmological imaging device comprising an objective lens, an interference optical system, an image forming unit, an optical member, and an analyzer. The interference optical system divides light from a light source into measurement light and reference light, causes the measurement light to become incident on a subject's eye via the objective lens, and detects interference light between the reference light and return light of the measurement light that has exited from the subject's eye and passed through the objective lens. The image forming unit forms an image of the subject's eye based on a detection result of the interference light which are acquired by the interference optical system. The analyzer analyzes a first detection result and a second detection result of the interference light to eliminate noise in the second detection result or in an image based on the second detection result.

Abstract: A terahertz-wave generation method of generating a terahertz wave in a direction satisfying a non-collinear phase-matching condition by making pump light incident on a nonlinear optical crystal capable of generating a terahertz wave by optical parametric effect, makes the pump light incident on the nonlinear optical crystal so that a peak excited power density is equal to or greater than a predetermined terahertz-wave lasing threshold and equal to or less than a predetermined laser damage threshold, and an average excited power density, is equal to or less than a predetermined photorefractive effect occurrence threshold, the pump light having a pulse width of 10 ps or more, the pulse width of 1 ns or less, and a repetition frequency of 1 kHz or more.

Abstract: An ophthalmological imaging device according to embodiments comprises an objective lens, an interference optical system, an optical scanner, a controller, and an image forming part. The interference optical system divides light from a light source into measurement light and reference light, causes the measurement light to become incident on a subject's eye via the objective lens, and detects interference light between the reference light and return light of the measurement light that has exited from the subject's eye and passed through the objective lens. The optical scanner deflects the measurement light. The controller controls the optical scanner such that a position away from an optical axis of the objective lens is set as a center to deflect the measurement light. The image forming part forms an image of the subject's eye based on a detection result of the interference light by the interference optical system.
