PROBLEM TO BE SOLVED: To keep measurement sensitivity or picture quality of an imaged picture of an ophthalmology apparatus even when a wavelength sweeping characteristic of light output from a wavelength sweeping type light source changes due to aging etc.SOLUTION: An ophthalmology apparatus comprises a calibration member that has a light path length of predetermined set length from a wavelength sweeping type light source apparatus and includes a reflection surface for reflecting light from the light source apparatus. The light source apparatus periodically sweeps a light wave to be output by outputting light from a light source through a periodically driven wavelength sweeping element. A controller acquires a reference spot image distribution function signal by acquiring, depending on a period of driving the wavelength sweeping element, a calibration interference signal output from a light receiving element in a specific acquisition period in the drive period; and adjusts, when a peak shape of the reference spot image distribution function signal is out of a preset shape range, timing of starting the acquisition period in the period of driving the wavelength sweeping element so that the peak shape of the reference spot image distribution function signal becomes within the preset shape range. |
