PROBLEM TO BE SOLVED: To provide an optical tomographic image photographing apparatus enabling an operator to easily recognize at least one of a distance between a probe and a tissue, and an acquisition situation of information by OCT (Optical Coherence Tomography) in a state that the operator closely watches a position of the probe carefully.SOLUTION: An optical tomographic image photographing apparatus divides light flux emitted from a light source into measurement light and reference light. The optical tomographic image photographing apparatus combines the measurement light radiated from a probe and reflected on a tissue inside a subject with the divided reference light to generate interference light. A CPU of the optical tomographic image photographing apparatus acquires at least one of distance information and acquisition state information from an interference signal of the interference light (S9, S10). The distance information is information on a distance between the probe and the tissue. The acquisition state information indicates an acquisition state of information in the depth direction of the tissue. The CPU controls at least one of visible light irradiation means, sound generation means, and vibration generation means on the basis of at least one of the distance information and the acquisition state information (S11).
