Abstract
An optical tomographic imaging apparatus includes a measurement light optical path length changing unit configured to change an optical path length of measurement light. In a case where any one of a plurality of imaging regions of an object (for example, a region of an anterior eye of a subject's eye and a region of a fundus of the subject's eye) is selected, the optical tomographic imaging apparatus can control the measurement light optical path length changing unit according to a size of an imaging range of a tomographic image corresponding to the selected imaging region.
Claims20
An optical tomographic imaging apparatus configured to obtain a tomographic image of an object based on light into which return light from the object irradiated with measurement light and reference light corresponding to the measurement light are combined, the optical tomographic imaging apparatus comprising:
- a measurement light optical path length changing unit configured to change an optical path length of the measurement light;
- a selection unit configured to select any one of a plurality of imaging regions of the object;
- and
- a control unit configured to control the measurement light optical path length changing unit according to a size of an imaging range of the tomographic image corresponding to the selected imaging region.
