El Gran Telescopio Canarias (GTC) es un telescopio con un espejo primario segmentado de 10.4 m, compuesto por 36 segmento hexagonales. Situado en el Observatorio del Roque de los Muchachos, en la Isla de la Palma, Canarias. ...
A thermal study of cellular motility by optical time-resolved correlation
(2012)
The study of motor properties of cells under appropriate physical-chemical conditions is a significant problem nowadays. The standard techniques presently used do not allow to evaluate neither large samples nor to control ...
Large-Range Polymer Optical-Fiber Strain-Gauge Sensor for Elastic Tendons in Wearable Assistive Robots
(MDIPSuiza, 2019)
This paper presents the development and validation of a polymer optical-fiber strain-gauge sensor based on the light-coupling principle to measure axial deformation of elastic tendons incorporated in soft actuators for ...

A theoretical approach to photosynthetically active radiation silicon sensor
(Elsevier, 2013-03)
Paste one version of a text here.This paper presents a theoretical approach for the development of low cost radiometers to measure photosynthetically active radiation (PAR). Two alternatives are considered: a) glass optical ...
Design of a phase-shifting interferometer in the extreme ultraviolet for high-precision metrology
(Optical Society of America, 2014)
The design of a phase-shift interferometer in the extreme ultraviolet (EUV) is described. The interferometer is expected to achieve a significantly higher precision as compared with similar instruments that utilize lasers ...
On the Use of the Main-sequence Knee (Saddle) to Measure Globular Cluster Ages
(2018)
In this paper, we review the operational definition of the so-called main-sequence knee (MS-knee), a feature in the color-magnitude diagram (CMD) occurring at the low-mass end of the MS. The magnitude of this feature is ...
