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.
Claims20
An image diagnosis apparatus comprising:
- a motor drive unit configured to be connected to a probe, the probe being configured to rotatably accommodate an imaging core including an optical transceiver configured to transmit and receive light, the motor drive unit being configured to rotate the imaging core;
- and
- a processor configured to:
- determine an effective pulse based on a pulse signal corresponding to the rotation of the imaging core from a pulse signal corresponding to an A line indicating a period of a light source and for switching a polarization state of the light transmitted from the optical transceiver according to the effective pulse;
- and
- acquire a signal of interference light between the light received by the optical transceiver and reference light according to the effective pulse.
