Abstract: A biological tissue inspection apparatus is disclosed. The biological tissue inspection apparatus comprises a stage and a probe. The probe comprises an optical imaging device, an optical interference detector, and a light guide. The probe acquires data regarding optical images and optical interference, through the optical imaging device and the optical interference detector. The stage or the probe moves such that a selected area of the inspection object is positioned in the FOV of the optical imaging device and of the optical interference detector. The light guide is configured such that illumination light from the optical imaging device and measurement light from the optical interference detector are coaxially emitted to the inspection object.
