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.

Abstract: Provided is a method of manufacturing a diamond knife for an ultra-microtome, including determining a shape and size of a knife, performing a multiphase flow analysis on movement of a droplet at a fore-end of the knife with the determined shape and size, processing a fine pattern to ensure hydrophobic property according to a result of the flow analysis, and grinding a blade of the knife after the processing of the fine pattern to minimize an interval between the pattern and the blade and, thus, a knife blade is always maintained in a wet state due to a droplet movement between a hydrophobic fine pattern and a hydrophilic surface to continuously generate ultrathin slices.
