Latest Patents

One of Aikawa's latest patents is a laser scan confocal microscope. This device generates fluorescence from an irradiated point on an inspection surface of a sample, which is then collected by an objective lens. Due to the magnification chromatic aberration of the objective lens, the fluorescence travels along a path shifted from the irradiation light. This fluorescence is transformed into a non-scan light by a galvano-scanner. The fluorescence then passes through a dichroic mirror into a plane-parallel plate, which is synchronized with the galvano-scanner by a computer. This setup corrects the shift and inclination of the optical axis caused by the chromatic aberration, allowing the fluorescence to form an image of the irradiation point on a pinhole plate using a collective lens.

Another notable patent involves a line of sight detection device calibration method. This method calibrates a device that measures the movement of a subject's eyeball while wearing eyeglasses. It detects the transmission point where the subject's line of sight passes through the lens of the eyeglasses. The calibration process includes measuring the movement of the eyeball with a baseline arranged at a predetermined position relative to the lens and calibrating the detection device based on the measurement results.
