Parallel illumination for depletion microscopy through acousto-optic spatial light modulation [PDF]
Several types of super-resolution microscopy, such as Stimulated Emission Depletion (STED), Reversible Saturable Optical Fluorescence Transitions (RESOLFT) or Switching Laser Mode (SLAM) microscopies, employ Laguerre-Gaussian beams (also called vortex or

High-frequency processing effects on three commercial polymers with different thermal properties under femtosecond laser irradiation [PDF]
The response of three of the most used commercial polymers (poly(vinyl chloride) (PVC), poly(ethylene terephthalate) (PET) and polypropylene (PP)) with different thermal properties under irradiation with high frequency (1 kHz-1 MHz) femtosecond (450 fs ...

Analysis of a vertically aligned liquid-crystal on silicon microdisplay for photonics applications [PDF]
We present the characterization results for an analogically addressed vertically aligned liquid crystal on silicon microdisplay (VA-LCoS). We show that it covers more than 360º phase modulation range at 1550 nm, and that in the visible the range ...

A study on disability glare vision in young adult subjects
The full assessment of the visual system must include the evaluation of the optical quality of the eye and neural visual functions. The objective evaluation of the retinal image quality is often carried out by computing the point spread function (PSF) of

Iterative-Trained Semi-Blind Deconvolution Algorithm to Compensate Straylight in Retinal Images
The optical quality of an image depends on both the optical properties of the imaging system and the physical properties of the medium in which the light travels from the object to the final imaging sensor.

Manufacturing reflection holographic couplers for see-through applications recorded in photopolymers without prisms: An experimental validation [PDF]
In the present work, the viability of a novel recording geometry to produce reflection holographic couplers is analyzed. Recalling the idea of previous works, photopolymers are used as the recording material, as they are well-suited for the intended see ...

Bragg gratings and BIO-Bragg-gratings in tapered optical fibers [PDF]
Tapered optical fibres are well-established devices for different applications, in order to exploit nonlinear effects, manage dispersion, excite azimuthal resonances in microresonators (so-called Whispering Gallery Modes).
