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: 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.
