METHOD FOR PERFORMING SELF-DIAGNOSIS PROCESS OF TOMOGRAPH

摘要

PURPOSE: A method for performing a self-diagnosis process of a tomograph is provided to perform a self-diagnosis process without an additional inspection system by using an additional optical fiber, a self-diagnosis mirror, and an additional control program. CONSTITUTION: The light transmitted into a probe(20) of a tomograph is switched by using an optical fiber(25) for diagnosis. The light is reflected on a magnetic diagnosis mirror(26) by controlling a voltage of an external electrode(21). The light is split by a beam splitter(10). A reference mirror(30) is displaced by an actuator. An interaction is generated between the light reflected on the magnetic mirror and the light reflected on the reference mirror by the beam splitter. The waveform and the intensity of the light interfered by beam splitter are analyzed by using an optical detector and a monitor. The intensity of the light is compared with a reference value if the optical interference is generated. An optical transmission error is reported if the intensity of the light is less than the reference value.
