Focus detection from digital in-line holograms based on spectral l1 norms.
A rapid focus-detection technique based directly on the spectral content of digital holograms is developed. It differs from previous approaches in that it does not need a full reconstruction of the image. The technique uses l(1) norms of object spectral components associated with the real and imaginary parts of the reconstruction kernel. Further, the l(1) norms can be computed efficiently in th...
متن کاملReconstruction from Digital Holograms by Statistical Methods
Conventional numerical reconstruction for digital holography using a filter applied in the spatial frequency domain to extract the primary image may yield suboptimal image quality because of the loss in highfrequency components and interference from other undesirable terms of a hologram. In this paper, we propose a new numerical reconstruction approach using a statistical technique. This approa...

12 September/October 2006 Published by the IEEE Computer Society 0272-1716/06/$20.00 © 2006 IEEE Among all the imaging techniques invented throughout the past several decades, computer graphics represent one of today’s most successful methods. Many areas in science, entertainment, education, and engineering would be unimaginable without the aid of 2D or 3D computer graphics. Interactivity provi...
متن کاملReconstruction of a complex object from two in-line holograms.
A novel numerical algorithm is proposed to reconstruct a complex object from two Gabor in-line holograms. With this algorithm, both the real and imaginary parts of the complex amplitude of the wave front in the object field can be retrieved, and the "twin-image" noise is eliminated at the same time. Therefore, the complex refractive index of the object can be obtained without disturbance. Digit...
متن کاملControlling depth of focus in 3D image reconstructions by flexible and adaptive deformation of digital holograms.
We show here that through an adaptive deformation of digital holograms it is possible to manage the depth of focus in 3D imaging reconstruction. Deformation is applied to the original hologram with the aim to put simultaneously in focus, and in one reconstructed image plane, different objects lying at different distances from the hologram plane (i.e., CCD sensor). In the same way, by adapting t...
