OPTICAL COHERENCE TOMOGRAPHY IMAGER, OPTICAL COHERENCE TOMOGRAPHY IMAGING METHOD, AND PROGRAM

摘要

Provided is an optical coherence tomography imager which reduces evaluation man-hours required to obtain a continuous, linear wavelength sweep operation which changes monotonically, while utilizing a wavelength tunable laser having a structure that is less susceptible to mechanical disturbances. This coherence tomography imager is provided with a wavelength tunable light source, a branching means, a radiating means, a photoelectric conversion measuring means, and a processor. The wavelength tunable light source outputs light having an output light wavelength determined by a plurality of light source drive parameters. The branching means causes the output light from the wavelength tunable light source to branch into object light and reference light. The radiating means radiates the object light onto an object being measured. The photoelectric conversion measuring means causes the object light scattered from the object being measured and the reference light to interfere, and guides the resulting light to a light receiver to obtain an interference light intensity measured value. The processor rearranges the interference light intensity measured values on the basis of the output light wavelength.
