Journal ArticleDOI
Space–bandwidth product of optical signals and systems
TL;DR: A quasi-geometrical representation of the space–bandwidth product in the Wigner domain is claimed to be more useful than a pure number that counts the degrees of freedom of the system.
Journal ArticleDOI
Fast algorithms for free-space diffraction patterns calculation
TL;DR: A fast algorithm based on the Fractional Fourier transform allow accurate evaluation of the Fresnel integral from object to Fraunhofer domain in a single step.
Journal ArticleDOI
Fractional wavelet transform.
TL;DR: The wavelet transform, which has had a growing importance in signal and image processing, has been generalized by association with both the wavelettransform and the fractional Fourier transform.
Journal ArticleDOI
Superresolution digital holographic microscopy for three-dimensional samples
TL;DR: An approach that allows superresolution imaging of three-dimensional (3-D) samples by numerical refocusing is presented in the field of digital holographic microscopy and a time multiplexing superresolved approach to overcome the Abbe's diffraction limit is presented.
Journal ArticleDOI
Three-dimensional mapping and range measurement by means of projected speckle patterns.

TL;DR: A novel approach for three-dimensional measurements that includes the projection of coherent light through ground glass that generates random speckle patterns on the object or on the camera, depending if the configuration is transmissive or reflective.
