1. Investigation on spectral-domain optical coherence tomography using a tungsten halogen lamp as light source

    Abstract  The objective of this research was to investigate a new detection method using a thermal light source in a spectral domain optical coherence tomography (SDOCT) operation to improve both image acquisition rate and axial resolution economically. A tungsten halogen lamp was chosen as the illumination source and a Michelson fiber interferometer was employed to generate the interference pattern of an object collected by a spectrometer; the inner structure of the object was obtained from the interference pattern by a Fourier transform. An experiment was performed by measuring a thin film coated on a glass base with the system, and ...
