摘要:
An ophthalmic imaging apparatus comprises: a laser emitter that includes an ultrashort pulse light source and emits a laser beam with a tunable wavelength in a predetermined visible wavelength range an irradiation optical system that includes a scanner for scanning the laser beam two-dimensionally and irradiates the laser beam emitted from the laser emitter to a predetermined portion of an examinees eye a light receiving optical system including an apertured plate placed in a substantially conjugate position of a focal point of the laser beam on the predetermined portion and a light receiving element for receiving the laser beam reflected by the predetermined portion and passed through the apertured plate a controller that controls the laser emitter to continuously change a central wavelength of the laser beam in a predetermined visible wavelength range and controls the scanner in association with the wavelength change of the laser beam to two-dimensionally change an irradiation position of the laser beam a memory that stores a light reception signal of the light receiving element associated with the wavelength change of the laser beam and the irradiation position change of the laser beam and a display, the controller being adapted to display an image of the predetermined portion on the display based on the light reception signal stored in the memory.
