Nowadays, taking advantage of polarization allows enhancing the contrast of a detected object and extending the information of the scene compared to conventional intensity imagery, as the information added by polarimetric ...

In this paper we present a technique based on self-mixing interferometry as a method for the acquisition and reconstruction of the arterial pulse wave. A modification of the classic fringe counting reconstruction algorithm ...

Lidar imaging systems are one of the hottest topics in the optronics industry. The need to sense the surroundings of every autonomous vehicle has pushed forward a race dedicated to deciding the final solution to be ...

We propose a new confocal device for flow profiling in microcapillaries. A viewfinder system is developed using a visible light microscope, allowing focusing with high precision an 830 nm Fabry-Perot laser diode on a ...

Optical feedback interferometry (OFI) sensors are experiencing a consistent increase in their applications to biosensing due to their contactless nature, low cost and compactness, features that fit very well with current ...

We present Megacam deep optical images (g and r) of Malin 1 obtained with the 6.5m Magellan/Clay telescope, detecting structures down to ~ 28 B mag arcsec-2. In order to enhance galaxy features buried in the noise, we use ...

La obtención de imágenes en condiciones climatológicas adversas (como niebla, lluvia y neblina), es uno de los problemas que afecta actualmente la investigación en el campo de la navegación, como resultado del creciente ...

We have recently proposed differential optical feedback interferometry as a convenient method to measure nanometric displacements. In this paper, we present experimental results to support the proposed method. The acquisition ...
