Application Number: JP,2022-018011
Category (FI): G02B6/12,351,G02B6/125,G02B6/12,336,G02B6/12,361,G01N21/17,630
Stage: PROBLEM TO BE SOLVED: To provide a new improved optical coherence tomographic device capable of, for example, inhibiting decrease in measurement accuracy due to manufacturing variations or the like.SOLUTION: The optical coherence tomographic device comprises: a light source part outputting light, capable of changing the wavelength of light to be outputted; a branch part splitting light from the light source part into irradiation light and reference light; a reference optical system transmitting the reference light from the branch part; an irradiation optical system transmitting the irradiation light from the branch part to irradiate an object therewith, and transmitting reflected light of irradiation light from the object; an interference part generating interference light generated by interference of the reflected light from the irradiation optical system and the reference light from the reference optical system; an interference light output part outputting interference light; and a coupling element functioning as the branch part and interference part. The reference optical system, the coupling element and the interference light output part are configured by a waveguide formed on a substrate and integrated on the substrate.SELECTED DRAWING: Figure 1 (Grant)
