Abstract: Provided is a common-path optical fiber-based handheld parallel optical coherence tomography (OCT) apparatus, including a probe configured to receive the light from a broadband light source and illuminate a measurement target, wherein the probe may include an inner space through which the light passes, a collimator configured to collimate the light incident to the inner space, a diffraction grating configured to diffract the light having passed through the collimator, a galvanometer scanner configured to reflect the light having passed through the diffraction grating, an objective lens configured to concentrate the reflected light on a focal point, and an interferer configured to acquire an interfered light by reflecting at least a portion of the light having passed through the objective lens.
