Abstract:
An ophthalmic imaging device for capturing a tomographic image of an eye, includes: an OCT optical system detecting interference of reference light and measurement light; a measurement optical system including an optical scanner and an objective optical system, the optical scanner being configured to deflect the measurement light to perform scanning with the measurement light; a driver configured to displace a relative position of the optical scanner with respect to the objective optical system in an optical axis direction; and a controller configured to control the driver to adjust a turning position of the measurement light in the optical axis direction. The controller changes the turning position between a first position corresponding to a first depth band of the eye and a second position corresponding to a second depth band of the eye which is different from the first depth band.
