Abstract
An optical coherence tomographic imaging apparatus capable of shortening the time required for focus adjustment and reducing the burden on an object is provided. The apparatus includes a first focus unit that moves a first optical focus member disposed in a light-receiving optical system of an optical observation system that obtains an observed image of an object, and a second focus unit that moves a second optical focus member disposed in an optical interference system that acquires a tomographic image of the object in conjunction with a movement of the first optical focus member.
