Publikováno v: Optics Continuum. 2:361

Diffraction calculation techniques based on Fourier transform, such as Fresnel diffraction, are essential in computational optics. Notably, zero padding is applied in diffraction calculations to manipulate sampling pitch and convolution calculations.

Phase retrieval using hologram transformation with U-Net in digital holography

Autor: Yuki Nagahama

Publikováno v: Optics Continuum. 1:1506

Digital holography is a method of recording light waves emitted from an object as holograms and then reconstructing the holograms using light wave propagation calculations to observe the object in three dimensions. However, a problem with digital hol

Computational ghost imaging (CGI) is a single-pixel imaging technique that exploits the correlation between known random patterns and the measured intensity of light transmitted (or reflected) by an object. Although CGI can obtain two- or three-dimen
