摘要:
An ophthalmic apparatus (10) is provided with a light source (12), an optical measurement system (24, 72, 48), an optical reference system (24, 22), an optical calibration system (24, 72, 74), a light receiving element (26), and a processor. The light receiving element (26) receives an interference light for measurement produced by both the reflected light guided by the optical measurement system (24, 72, 48) and the reference light guided by the optical reference system (24, 22), and also receives an interference light for calibration produced by the calibration light guided by the optical calibration system (24, 72, 74) and the reference light guided by the optical reference system (24, 22). The processor (64) determines a position of a measuring portion inside an eye (100) to be examined by Fourier-analyzing the interference light for measurement and the interference light for calibration.
