DC term filtering techniques in digital holography
In numerical hologram reconstruction like in optical holography, there exist different diffraction orders, which many times produce difficulties for the image visualizations. In numerical reconstruction, the filtering of ...
Phase-difference images by digital holography applied to 3D surface contouring
(Academia Colombiana de Ciencias Exactas Físicas y Naturales, 2005-06)
The problem to determine the 3D-contour of objects with all sizes and shapes is a hot topic in diverse fields of optical research and engineering. Through the use of the numerical reconstruction of digital recorded holograms, ...
