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 ... -
High sampling rate single-pixel digital holography system employing a DMD and phase-encoded patterns
Optical Society of America (2018)A single-pixel digital holography system with phase-encoded illumination using a digital micromirror device (DMD) as a spatial light modulator (SLM) is presented. The enhanced switching rate of DMDs, far exceeding the ...

Optical Filter Based on a Spatially Patterned Kinoform Diffractive Lens
Institute of Electrical and Electronics Engineers (IEEE) (2009)We demonstrate a compact all-diffractive setup for spectral synthesis. The system is composed of a circularly symmetric mask attached to a kinoform diffractive lens. Following diffraction-based analysis, a Fourier transform ... -
Optical filters with fractal transmission spectra based on diffractive optics
Optical Society of America (2009)The duality between the axial irradiance distribution originated by any circularly symmetric diffracting aperture under monochromatic illumination and its diffracted spectral intensity at a fixed on-axis point under broadband ...

Phase calibration of spatial light modulators by means of Fresnel images
Institute of Physics (2009)Reliable application of spatial light modulators (SLMs) as programmable diffractive optical elements requires a thorough calibration. In this paper, we propose a method for calibrating SLMs based on the evaluation of ...

Single-pixel imaging through non-homogeneous turbid media with adaptive illumination
Optica Publishing Group (2024-03-29)The presence of scattering media limits the quality of images obtained by optical systems. Single-pixel imaging techniques based on structured illumination are highly tolerant to the presence of scattering between the ...

Spatial-chirp compensation in dynamical holograms reconstructed with ultrafast lasers
American Institute of Physics (2008)A computer generated hologram (CGH) reconstructed with a sub-100-fs laser pulse at the focal plane of a conventional refractive lens experiences a large amount of spatial chirp. We report the shaping of a 12 fs laser pulsed ...

Spectral analysis of femtosecond pulse diffraction through binary diffractive optical elements: theory and experiment
Optical Society of America (2008)We report on the changes in the spectrum of a femtosecond pulse originated by diffraction of the ultrashort waveform through a circularly symmetric binary diffractive optical element. The analysis is performed in the ...

Tunable telephoto: governable Fourier spectrum anamorphic scaling
(2021-02-18)We discuss the Gaussian design of a device that controls the scale, in an anamorphic fashion, of Fraunhofer diffraction patterns. The device uses two pairs of varifocal cylindrical lenses. For spherical lenses, the optical ...

Use of polar decomposition of Mueller matrices for optimizing the phase response of a liquid-crystal-
on-silicon display
Optical Society of America (2008)We provide experimental measurement of the Mueller matrices corresponding to an on-state liquid-crystal-on-silicon display as a function of the addressed voltage. The polar decomposition of the Mueller matrices determines ...
