Dual-mode optical microscope based on single-pixel imaging
(Elsevier, 2016-03)
We demonstrate an inverted microscope that can image specimens in both reflection and transmission modes simultaneously with a single light source. The microscope utilizes a digital micromirror device (DMD) for patterned ...
Computational imaging with a balanced detector
(Nature Publishing, 2016-06-29)
Single-pixel cameras allow to obtain images in a wide range of challenging scenarios, including broad regions of the electromagnetic spectrum and through scattering media. However, there still exist several drawbacks that ...
Free-Motion Beam Propagation Factor Measurement by Means of a Liquid Crystal Spatial Light Modulator
(Institute of Electrical and Electronics Engineers, 2012)
In contrast to the mechanical scanning procedure
described in the standard ISO/DIS 11146, the use of electronically tunable focal length lenses has proved its capability for the
measurement of the laser beam propagation ...
Single-pixel digital holography with phase-encoded illumination
(Optical Society of America, 2017-02-23)
We demonstrate imaging of complex amplitude objects through digital holography with phase-structured illumination and bucket detection. The object is sampled with a set of micro-structured phase patterns implemented onto ...
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 ...
Fast compressive Raman bio-imaging via matrix completion
(Optical Society of America, 2019)
Raman microscopy is a powerful method combining non-invasiveness with no special sample preparation. Because of
this remarkable simplicity, it has been widely exploited in many fields, ranging from life and materials ...
Photon Counting 3-D Object Recognition Using Digital Holography
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
We present an analysis of the recognition performance of 3-D objects reconstructed
from digital holograms recorded under photon counting conditions. The digital
holograms are computed by applying four-step phase-shifting ...
Resolution analysis in computational imaging with patterned illumination and bucket detection
(Optical Society of America, 2014)
In computational imaging by pattern projection, a sequence of microstructured light patterns codified onto a programmable spatial light modulator is used to sample an object. The patterns are used as generalized measurement ...
