      Optical Coherence Tomography Apparatus And Optical Coherence Tomography Method

      The optical coherence tomography apparatus (1) comprises: a light source (11) that irradiates laser light; an optical splitter (12) that divides the laser light into measuring light that is irradiated on a subject (S) and reference light that is irradiated on a reference mirror (21); a probe (30) that receives scattered light returning after being scattered inside the subject (S); and an optical multiplexer (16) that combines reflected light returning after being reflected by the reference mirror (21) with the scattered light to generate interference light. The apparatus analyzes the interference light and generates an optical coherence tomographic image. The ...

    2. 24 mm Depth Range Discretely Swept Optical Frequency Domain Imaging In Dentistry

      A large depth range is needed if optical coherence tomography (OCT) is to be used to observe multiple teeth simultaneously. A discretely swept optical frequency domain imaging system with a 24-mm depth range was made by using a superstructure-grating distributed Bragg reflector (SSG-DBR) laser as th ... [Proc. SPIE 7162, 716208 (2009)] published Wed Feb 18, 2009.
