Abstract
A dental optical coherence tomography apparatus for measuring tissue in a stomatognathic region of a living body or an artificial composition in the stomatognathic region as a measured object includes: a variable wavelength light source (); a light splitting portion () that splits light-source light emitted from the variable wavelength light source () into reference light () and measuring light (); an interference portion () that causes the measuring light () and the reference light () to interfere with each other, thereby generating interference light; a photodetection portion () that measures the interference light; and an arithmetic portion () that generates an image of a measured object () by Fourier transforming or inverse Fourier transforming the intensity of the interference light, whose wavelength changes with time, that has been detected by the photodetection portion for each of the wavelengths. Accordingly, an optical coherence tomography apparatus applicable to dental measurement can be provided.
