Laser scanning ophthalmoscope using alternating wavelengths generates scanning motion to correct values for images formed by illumination wavelengths taken from images already formed

摘要

Various alternating wavelengths in a scan system (SC) illuminate an eye (Auge) during an initial scanning motion. Two images are formed for primary and secondary wavelengths. Several of these images are compared with each other. Object displacement is used to define corrective values for images formed by other illumination wavelengths. They are defined with an illumination wavelength taken from images already formed.
