Abstract
An image diagnosis apparatus determines an effective pulse based on a pulse signal corresponding to the rotation of an imaging core from a pulse signal corresponding to an A line indicating a period of a light source and switches the polarization state of light transmitted from an optical transceiver according to the effective pulse. According to the effective pulse, the image diagnosis apparatus acquires a signal of interference light between the light received by the optical transceiver and reference light.
