How wavelength scanning optical coherence tomography apparatus and tomography

摘要

The present invention without requiring the addition of high performance and complex devices of the apparatus, the user provides a wavelength scanning optical coherence tomography apparatus that can acquire a tomographic image in a more desired mannerA wavelength scanning optical coherence tomography apparatus, changes the wavelength scanning light source for outputting a wavelength scanning light which wavelength is being scanned, in the course of the scanning of the wavelength, the wave number of the wavelength scanning light by a predetermined change amount and the wave number equal interval clock output section for outputting the k-clock signal K to repeat rising and falling alternately at the timing, and wavelength scanning light, the object reflected light obtained by reflecting the wavelength scanning light at the object to be shot If the interference signal C indicating the intensity of the interference light, k-clock with the first sampling unit 210 for sampling at the timing of the rise of the signal K, the interference signal C, sampling at the timing of the falling edge of the k-clock signal K It includes a second sampling unit 211 for, theFIELD 2
