Abstract: A method of operating an electronic apparatus configured to generate holotomographic image data according to one embodiment of the present disclosure includes: acquiring fusion data from a fusion imaging apparatus in which a holographic tomography apparatus and a super-resolution fluorescence microscope are combined, in which the fusion data includes input data corresponding to holotomographic image data and output data corresponding to image data of the super-resolution fluorescence microscope; generating a cross-modal inference-based deep learning engine configured to generate a super-resolution tomographic image based on the input data and the output data; and acquiring a molecule-specific tomographic image using the deep learning engine, wherein the molecule-specific tomographic image has nano-resolution.

Abstract: Provided is an apparatus and method for encoding a hologram and evaluating a holographic image quality for an amplitude-modulated hologram. A hologram encoding method may include acquiring three-dimensional (3D) information of a scene or an object; generating hologram information based on the 3D information; deriving a real number hologram function by extracting a real number part and an imaginary number part from the hologram information; determining an intermediate hologram function based on a sign characteristic of the real number hologram function; and determining encoded hologram information based on the intermediate hologram function.
