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, ...
Evaluation between methods for the color measurement in holograms by using a CMOS-RGB camera and a spectrometer
Many models and methods commonly used in colorimetry have been incorporated to the study and knowledge of the colorimetric properties in the reflection color holograms; these methods have reported the possibilities of color ...
Reduction of speckle noise in digital holography
A fundamental problem in holography, as well optical as digital, is the presence of speckle noise in the reconstruction process -- Many approaches have been carried out in order overcome such a problem, ranging from altering ...
