THREE-DIMENSIONAL RETINA IMAGE GENERATION DEVICE

摘要

Provided is a smaller, cheaper three-dimensional retinal image generation device that has high resolution and is easy to use. A provided optical coherence eye-fundus tomography device (100) comprises: a light-source unit (110) that emits a source light beam; a reference-light unit (130) that reflects a reference light beam; an inspection unit (140) that illuminates an object with an object-scanning light beam, reflecting said light beam off the object; and an image-detection unit (150) that obtains a tomographic image of the object on the basis of an interference light beam resulting from interference between the object-reflected light beam and the reflected reference light beam. The light-source unit (110), for example, has a depth of focus of 300 µm or greater and emits a light beam having a lateral resolution greater than 6 µm × 6 µm in a plane perpendicular to the direction of motion of the object-scanning light beam.
