Abstract: The present disclosure relates to a confocal imaging apparatus using a chromatic aberration lens, which is capable of quickly implementing multiple tomographic images by making it possible to quickly scan the entire object without moving the light source or the object. Since the present invention is configured to generate a three-dimensional image using multiple tomographic images by a chromatic aberration lens without moving the light source or the object up and down, there is an effect of remarkably shortening the time it takes to implement the multiple tomographic images.

Abstract: A fluorescent image acquisition and projection apparatus for real-time visualization of an invisible fluorescent signal is provided. The apparatus visualizes an invisible fluorescent signal generated from a target object (a tissue of a living body, a cell of a living body, or the like) by using a photodetection unit and a projector in real time. The apparatus directly projects a visualized fluorescent signal onto a region of the target object where the invisible fluorescent signal is generated, thereby enabling users to determine and confirm the generation location of the fluorescence with the naked eye.

Abstract: A fluorescent image acquisition and projection method includes the steps of generating, by a plurality of light sources, invisible fluorescence under control of a control device and obtaining, by a detection unit, a signal of an invisible fluorescent image from a target object. The method further includes the steps of receiving from the detection unit and processing the invisible fluorescent image signal of the target object into a visible fluorescent signal, transmitting the visible fluorescent signal to a projector unit, and projecting, by the projector unit, the visible fluorescent signal onto the target object.

Abstract: Disclosed is a photonic crystal-fiber coupler that can distribute light while maintaining the inherent optical properties of photonic crystal fibers. The inventive photonic crystal-fiber coupler comprises at least two photonic crystal fibers and at least one coupling region longitudinally formed along the part of each photonic crystal fiber. Each photonic crystal fiber has a core portion and a cladding portion and includes a plurality of longitudinal holes formed in such a manner to surround the core portion.
