This paper reviews recent developments of non-contact three-dimensional (3D) surface
metrology using an active structured optical probe. We focus primarily on those active non …

In the realm of optical technologies, the integration of nature's designs and modern
engineering has paved the way for groundbreaking innovations. Bio-inspired tunable optics …

We present a first implementation of an optical encryption setup in the fractional Fourier
domain using an electrically focus-tunable lens. Fractional Fourier transform cryptosystems …

Myopia is one of the most common ocular disorders worldwide and the leading cause of
visual impairment in children. The elongation of axial length in the eyes with medium and …

Saturated excitation microscopy, which collects nonlinear fluorescence signals generated by
saturation, has been proposed to improve three-dimensional spatial resolution. Differential …

This paper presents the use of a deformable mirror (DM) configured to rapidly refocus a
microscope employing a high numerical aperture (NA) objective lens. An Alpao DM97-15 …

Tunable spherical fluidic lenses are among the most essential components in adaptive
optics. However, fabricating cylindrical tunable lenses has proven more challenging, mainly …

Autorefraction is an objective way to determine the refractive error of the eye, without the
need for feedback by the patient or a well-educated practitioner. To make refractive …

Today, multiple technological instruments facilitate the work of the researcher. These
instruments are provided with some features given by the manufacturer. However, it is …

El proceso de la visión que finaliza con la sensación de ver algo, es decir, con la percepción
de un estímulo visual, comienza con la formación de la imagen del mundo sobre la retina …
