Optical coherence microscopy (OCM) is a non-destructive 3-dimentional (3D) imaging technique with micrometer-scale resolution, which is based on optical coherence tomography (OCT) and confocal microscopy. Recently, it has been demonstrated that the OCT imaging depth is improved by using 1700 nm spectral band, so called “optical window 3”, due to the lower light absorption and a local minimum of water absorption in the wavelength region. In this presentation, we report high-resolution spectral-domain OCM (SD-OCM) at the 1700-nm spectral band for improving the imaging acquisition speed of 1700-nm OCM.
