发明名称 OPTICAL INTERFERENCE IMAGE DIAGNOSING APPARATUS, AND ITS PROCESSING METHOD
摘要 <p>Intended is to calibrate the optical path difference between a measurement light and a reference light precisely and easily. Provided is an optical interference tomographic diagnosis apparatus, which is connected with an optical probe for irradiating a measurement object with a measurement light and receiving the reflected light from the measurement object. The apparatus divides the light outputted from the light source, into the measurement light and the reference light, and causes the reflected light and the reference light to interfere so that it acquires the reflection intensity distribution in the emanating direction of the optical probe thereby to form the image of the measurement object. The apparatus comprises means (405) for extracting one unit from the reflection intensity distribution, means (328) for recognizing, in case a predetermined reference position, as discriminated on the basis of the intensity distribution extracted, in the emanating direction of the optical probe is misaligned from a predetermined position, the distance between the reference position and the predetermined position as a deviation, and means (326) for adjusting the optical path length of the measurement light or the reference light on the basis of that deviation.</p>
