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, ...
Improvement of the signal-to-noise ratio in digital holography
(Sociedad Mexicana de Física, 2005-02)
A fundamental problem in optical and digital holography is the presence of speckle noise in the reconstruction process, which essentially diminishes the signal to noise ratio (SNR). For many applications, that reduction ...
