Measurement apparatus, ophthalmologic imaging apparatus, control method, and storage medium

An ophthalmologic imaging apparatus comprising:

• a measuring light focusing unit configured to focus measuring light radiated to a subject's eye on the subject's eye;
• an aberration measurement unit configured to measure aberration based on return light of the measuring light having passed through the measuring light focusing unit;
• an adaptive optical system configured to correct the aberration based on the aberration measured by the aberration measurement unit;
• a first imaging light source configured to irradiate the subject's eye with first light for capturing a first image;
• a first imaging light focusing unit configured to focus the light from the first imaging light source on the subject's eye;
• a first imaging unit configured to detect the light from the first imaging light source having passed through the adaptive optical system and the first imaging light focusing unit to acquire a first image of an object;
• a second imaging light source configured to irradiate the subject's eye with second light for capturing an image having a field angle wider than that of the first image;
• a second imaging light focusing unit configured to focus the light from the second imaging light source on the subject's eye;
• a second imaging unit configured to detect the light from the second imaging light source having passed through the second imaging light focusing unit to acquire a second image of the object;
• a housing configured to store the measuring light focusing unit, the aberration measurement unit, the adaptive optical system, the first and second imaging light sources, the first and second imaging light focusing units, and the first and second imaging units;
• a changing unit configured to change a position of the housing;
• a jaw receiver configured to adjust a position of a head of the subject;
• and
• a storing unit configured to store, in a storage unit, at least one of a state of the measuring light focusing unit, a state of the first imaging light focusing unit, a state of the second imaging light focusing unit, the position of the housing, and a position of the jaw receiver when the first image is captured in association with identification information of the subject's eye.

A method for controlling an apparatus for measuring aberration based on return light of measuring light radiated to an object, the method comprising:

• storing, in a storage unit, information indicating a state of a focusing unit configured to focus the measuring light on the object when the aberration is measured in association with information of a subject;
• acquiring identification information of the object;
• acquiring, from the storage unit, information indicating a state of the focusing unit associated with the object by using the acquired identification information of the object;
• and
• controlling focusing of the measuring light based on the acquired information indicating the state of the focusing unit.

A method for controlling an ophthalmologic imaging apparatus including a measurement unit configured to change a position for capturing a first image of a subject's eye irradiated with light having passed through an aberration correction device for correcting aberration to be imaged and capturing a second image having a field angle wider than that of the first image, and a jaw receiver configured to adjust a position of a head of the subject, the method comprising:

• storing, in a storage unit, at least one of information indicating a position of the measurement unit of the ophthalmologic imaging apparatus, information indicating a position of the jaw receiver, information indicating a state of a focusing unit configured to focus measuring light for measuring aberration on the subject's eye, information indicating a state of a focusing unit configured to focus imaging light for capturing the first image, and information indicating a state of a focusing unit configured to capture the second image having the field angle wider than that of the first image when the first image is captured in association with identification information of the subject's eye;
• acquiring, from the storage unit, the information associated with the subject's eye by using identification information of a specific subject's eye;
• and
• controlling each unit of the ophthalmologic imaging apparatus based on the information.
