1.
Perciante C, Ferrari J
Appl Opt
. 2019 Dec;
58(35):9570-9576.
PMID: 31873555
The aim of the present work is to study the dependence of the light-induced optical density, i.e., the color-center concentration, as a function of the distance traveled inside a photochromic...

Ferrari J, Flores J, Ayubi G, Frins E
Opt Express
. 2017 Dec;
25(24):29965-29970.
PMID: 29221031
We describe a robust interferometer with external phase-shift control that does not require moving parts. The optical architecture resembles a common-path device in which the interfering waves propagate together in...

Silva A, Flores J, Munoz A, Ayubi G, Ferrari J
Appl Opt
. 2017 Oct;
56(18):5198-5203.
PMID: 29047570
Three-dimensional (3D) shape profiling by sinusoidal phase-shifting methods is affected by the non-linearity of the projector. To overcome this problem, the defocusing technique has become an important alternative to generate...

Generalized phase-shifting algorithms: error analysis and minimization of noise propagation: erratum
Ayubi G, Perciante C, Di Martino J, Flores J, Ferrari J
Appl Opt
. 2016 Nov;
55(28):7763.
PMID: 27828004
There are a couple of typos in our recent paper Appl. Opt.55(6), 1461-1469 (2016)APOPAI0003-693510.1364/AO.55.001461.

Appl Opt
. 2016 May;
55(9):2380-6.
PMID: 27140577
The convergence of optical imaging acquisition and image processing algorithms is a fast-evolving interdisciplinary research field focused on the reconstruction of images with novel features of interest. We propose a...

Appl Opt
. 2016 May;
55(13):3632-8.
PMID: 27140381
The identification and extraction (i.e., segmentation) of geometrical features is crucial in many tasks requiring image analysis. We present a method for the optical segmentation of features of interest from...

Appl Opt
. 2016 Feb;
55(6):1461-9.
PMID: 26906601
Phase shifting is a technique for phase retrieval that requires a series of intensity measurements with certain phase steps. The purpose of the present work is threefold: first we present...

Appl Opt
. 2016 Feb;
54(36):10586-91.
PMID: 26837021
We present some pattern recognition applications of a generalized optical Hough transform and the temporal multiplexing strategies for dynamic scale and orientation-variant detection. Unlike computer-based implementations of the Hough transform,...

Appl Opt
. 2015 Nov;
54(30):8827-34.
PMID: 26560367
In order to overcome the limitations of the sequential phase-shifting fringe pattern profilometry for dynamic measurements, a color-channel-based approach is presented. The proposed technique consists of projecting and acquiring a...

PMID: 26274689
The generalized Hough transform is a well-established technique for detecting complex shapes in images containing noisy or missing data. We present an efficient optical implementation of this transform using an...
