Phase and amplitude reconstruction in single-pixel transmission microscopy: a comparison of Hadamard, cosine, and noiselet bases
Optical Society of America (2021-08-10)Hadamard, cosine, and noiselet bases are implemented into a digital holographic microscope based on single-pixel imaging with the capability to retrieve images of complex objects. The object is illuminated with coherent ... -
Phase imaging by spatial wavefront sampling
Optical Society of America (2018)Phase-imaging techniques extract the optical path length information of a scene, whereas wavefront sensors provide the shape of an optical wavefront. Since these two applications have different technical requirements, ...

Pinpointing spatio-temporal interactions in wildfire patterns
Springer-Verlag (2012-12)The spatial and spatio-temporal patterns of wildfire incidence and their relationship to various geographical and environmental variables are analyzed. Such relationships may be treated as components in particular point ... -
Place and city: Operationalizing sense of place and social capital in the urban context
John Wiley & Sons Ltd (2017)The academic interest in social concepts in city contexts, such as sense of place and social capital, has been growing in the last decades. We present a systematic literature review that confirms the strong relationship between ...
