Direction-sensitive transverse velocity measurement by phase-modulated structured light beams
Rosales Guzmán, Carmelo; Hermosa, Nathaniel; Belmonte Molina, Aniceto; Pérez Torres, Juan (2014-09-15)
Article
Accés restringit per política de l'editorialThe use of structured light beams to detect the velocity of targets moving perpendicularly to the beam's propagation axis opens new avenues for remote sensing of moving objects. However, determining the direction of motion ... -
Experimental detection of transverse particle movement with structured light
Rosales Guzmán, Carmelo; Hermosa, Nathaniel; Belmonte Molina, Aniceto; Pérez Torres, Juan (MACMILLAN PUBLISHERS LIMITED, 2013-10-02)
Article
Accés obertOne procedure widely used to detect the velocity of a moving object is by using the Doppler effect. This is the perceived change in frequency of a wave caused by the relative motion between the emitter and the detector, ... -
Frequency conversion of structured light
Steinlechner, Fabian; Hermosa, Nathaniel; Pruneri, Valerio; Pérez Torres, Juan (Macmillan Publishers, 2016-02-15)
Article
Accés obertCoherent frequency conversion of structured light, i.e. the ability to manipulate the carrier frequency of a wave front without distorting its spatial phase and intensity profile, provides the opportunity for numerous novel ... -
Measuring the translational and rotational velocities of particles in helical motion using structured light
Rosales Guzmán, Carmelo; Hermosa, Nathaniel; Belmonte Molina, Aniceto; Pérez Torres, Juan (2014-06-30)
Article
Accés obertWe measure the rotational and translational velocity components of particles moving in helical motion under a Laguerre-Gaussian mode illumination. The moving particle reflects light that acquires an additional frequency ... -
Nanostep height measurement via spatial mode projection
Hermosa, Nathaniel; Rosales Guzmán, Carmelo; Pereira, S. F.; Pérez Torres, Juan (2014-01-15)
Article
Accés obertWe demonstrate an optical scheme for measuring the thickness of thin nanolayers with the use of light beam ’ s spa- tial modes. The novelty in our scheme is the projection of the beam reflected by the sample onto a ... -
Puentes, Hermosa, and Torres reply
Puentes, Graciana; Hermosa, Nathaniel; Pérez Torres, Juan (2013-07-10)
Article
Accés obertA Reply to the Comment by A. K. Pan and P. K. Panigrahi. -
Transverse Doppler effect using engineered optical beams
Rosales Guzmán, Carmelo; Hermosa, Nathaniel; Belmonte Molina, Aniceto; Pérez Torres, Juan (2013)
Text en actes de congrés
Accés restringit per política de l'editorialWhen a light beam with a transverse spatially-varying phase is considered for optical remote sensing, in addition to the usual longitudinal Doppler frequency shift of the returned signal induced by the motion of the ...
