Abstract: Provided is a fast parallel optical coherence tomographic image generating method including dispersing light into N spectral regions Δλ1 through ΔλN sequentially from a low frequency wavelength to a high frequency wavelength, the light being emitted from a broadband light source of a fast parallel optical coherence tomographic image generating apparatus, N being an integer greater than or equal to 2, splitting the light emitted from the broadband light source to be incident on a sample and a reference mirror, partitioning the sample into N image regions P1 through PN, discretely controlling a beam scanner such that the light emitted from the broadband light source is incident on the sample at a position changed by a preset distance, acquiring an interference spectral image through interference light formed in response to interference of measurement light and reference light, and generating a tomographic image of the sample using the interference spectral image.
