Analysis on image recovery for digital Fresnel hologram with aliased fringe generated from self-similarity of point spread function
Byung Gyu Chae
We analyze the aliasing phenomenon for digital Fresnel hologram with an enhanced numerical aperture (NA). The enhanced-NA digital hologram acquired computationally or optically at…

Methods for extending viewing-angle of holographic image by using digital hologram with high numerical aperture
Byung Gyu Chae
We investigate the angular field of view (AFOV) of a holographic image reconstructed from the digital Fresnel hologram in holographic display. The theoretical analysis reveals that…

Neural network image reconstruction for magnetic particle imaging
Byung Gyu Chae
We investigate neural network image reconstruction for magnetic particle imaging. The network performance depends strongly on the convolution effects of the spectrum input data. Th…
