Shaping the Amplitude and Phase of Laser Beams by Using a Phase-only Spatial Light Modulator
Journal of Visualized Experiments (2019-01-29)The aim of this article is to visually demonstrate the utilization of an interferometric method for encoding complex fields associated with coherent laser radiation. The method is based on the coherent sum of two uniform ... -
Signal-to-noise ratio of single-pixel cameras based on photodiodes
Optical Society of America (2018-03-01)Single-pixel cameras have been successfully used in different imaging applications in the last years. One of the key elements affecting the quality of these cameras is the photodetector. Here, we develop a numerical model ... -
Significance tests for covariate-dependent tredns in inhomogeneous spatio-temporal point processes
Springer Verlag (2014-03)Modeling and inference for spatial and spatio-temporal point processes is an issue that has been broadly investigated in the last years. Application fields such as forestry, epidemiology and ecology have been the main ...

Similarity measures of conditional intensity functions to test separability in multidimensional point processes
Springer-Verlag (2013-07)Separability in the context of multidimensional point processes assumes a multiplicative form for the conditional intensity function. This hypothesis is especially convenient since each component of a separable process may ...

Single-pixel imaging of the retina through scattering media
Optical Society of America (2019)Imaging the retina of cataractous patients is useful to detect pathologies before the cataract surgery is performed. However, for conventional ophthalmoscopes, opacifications convert the lens into a scattering medium that ...

Single-shot digital holography
by use of the fractional Talbot effect
Optical Society of America (2009)We present a method for recording in-line single-shot digital holograms based on the fractional Talbot effect. In our system, an image sensor records the interference between the light field scattered by the object and a ...
