Our Work

Wooptix is always working and researching, deepening more and more in the novelties of the technological sector and of each one of our technologies and solutions, it is a sector in constant movement in which new products appear every day. We frequently publish papers in various digital and physical media.

PREPRINT / The optics of the human eye at 8.6 micrometer lateral resolution / March 2021

Wooptix’ team with the collaboration of Damien Gatinel & Jack T. Holladay

In this work, we characterize the in vivo ocular optics of the human eye with a lateral resolution of 8.6 microns, which implies roughly 1 million measurement points for a pupil diameter of 9 mm. The results suggest that the normal human eye presents a series of hitherto unknown optical patterns. This discovery could have a great impact on the way we understand some fundamental mechanisms of human vision.

New high-resolution wave ophthalmic instrument for the characterizing ocular optics / February 2020

We present a new wave front sensing technique based on detecting the propagating light waves. This allows the user to acquire millions of data points within the pupil of the human eye; a resolution several orders of magnitude higher than current industry standard ophthalmic devices.

Wavefront phase imaging for global and local wafer geometry / February 2020

Wavefront phase imaging for global and local wafer geometry / February 2020

Juan Manuel Trujillo-Sevilla, Jose Manuel Ramos-Rodríguez, Jan Gaudestad

Wavefront phase imaging (WFPI) is a new technique to measure wafer geometry on a full wafer in a single image snapshot providing depth information for every pixel. The number of topography data points for the entire wafer will be proportional to the number of pixels in the image sensor, allowing for millions of data points to be acquired in less than a second.

Exposing parallelism of discrete radon transform / November 2019

Óscar Gómez, Ricardo Oliva, Gabriel A. Rodríguez, José G. Marichal

Discrete Radon Transform, DRT, is an integral transform that computes the complete set, in terms of slope and intercepts, of line integrals through a two-dimensional domain. It exhibits linearithmic computational complexity and avoids the usage of real numbers thanks to a divide and conquer, or multiscale, approach with a loose definition of discrete lines.

Wavefront Phase Imaging sensor (WFPI) / October 2019

José Manuel Rodríguez-Ramos, Alex Roqué, David Carmona, Jan Gaudestad

We will discuss here the applications of the Wavefront Phase Imaging sensor (WFPI) on Adaptive Optics (AO) for Astronomy. The WFPI sensor is based on registering the intensity distribution at two different optical planes by a conventional imaging sensor. In the geometrical approximation, the light can be considered as a collection of light rays which bends according to Snellen’s law.

Wave Front Phase Imaging of Wafer Geometry Using High Pass Filtering for Improved Resolution / October 2019

José Manuel Rodríguez-Ramos, Jan Gaudestad, Juan Manuel Trujillo

In this paper we show that Wave Front Phase Imaging (WFPI) has good enough lateral resolution and is sensitive enough to measure roughness on a silicon wafer by simply acquiring a simple image of the entire wafer. WFPI is achieved by measuring the reflected light intensity from monochromatic uncoherent light at two different planes along the optical path with the same field of view.
