Optical coherence tomography device which is capable of controling measuring position

摘要

Disclosed is an optical coherence tomography apparatus capable of accurately performing an operation distance adjustment and center alignment between an eye to be measured and an optical coherence tomography apparatus. The optical coherence tomography apparatus includes a mirroring optical system that irradiates the measurement measurement light onto a measurement target; An image photographing unit detecting an image of illumination light reflected from the measurement target and a miring light image reflected from the measurement target; A tomography imaging unit for radiating a signal light to the measurement object to capture an internal tomography image of the measurement object; Separating the path of the illumination light of the image pickup unit and the signal light of the tomography imaging unit reflected from the measurement object, and transmits the reflected image of the illumination light to the image pickup unit, and transmits the reflected signal light to the tomography imaging unit Dichroic mirrors; An objective lens for focusing signal light and illumination light incident or reflected from the measurement object; And an amount of vertical and horizontal movement of the optical interference tomography apparatus is calculated from the difference between the position of the mirroring optical image and the position of the optical axis of the optical interference tomography apparatus, and thus the optical interference tomography apparatus is vertically and horizontally And a controller for aligning the position of the miring light image with the optical axis of the optical coherence tomography apparatus.
