Biography
Telecommunications Engineer since 2003 from the Polytechnic University of Valencia, where he also obtained a Master’s degree in Communications in 2013. In addition, he holds a Master’s degree in Information Systems Management since 2011 from the Open University of Catalonia and has been certified in ITIL v3 Foundations since 2011. He began working as a student at Adapting S.L. in late 2001, programming web applications, accessing databases, and transforming large volumes of data into user-friendly interfaces. In mid-2002, he joined the AIDO Technological Institute, where he completed his studies and worked until 2006. Most of his work was related to artificial vision systems and their communications, both for synchronization and for transmitting results, as well as installing and configuring systems at client facilities. Between 2006 and 2007, he worked at Eines Systems S.L., a supplier for Ford Motor Company, designing and programming artificial vision systems for quality control and robot guidance on production lines. From mid-2007 to 2011, he worked at the Valencia Stock Exchange, managing communication systems, programming new financial protocols, and collaborating in quality verification of an internal back-end program. In 2011, Martin joined Lifesequencing S.L., a company specialized in genomic research and massive DNA sequencing, where he developed programs to connect the results of open-source DNA alignment tools with internal applications and reporting systems. From 2012 until mid-2025, he worked in the Optics Department as a Research Support Technician, developing software for microscopy, holography, and other applied vision systems. He is currently an Assistant Professor in the Computer Science Department at the School of Engineering.

LENSLESS MICROSCOPY: Digital in-line holographic microscopy (DIHM) in combination with numerical imaging reconstruction proposes an extremely simplified layout while retain the advantages provided by holography with enhanced capabilities derived from digital processing algorithmic. DIHM supposes a modern realization of the original idea proposed by Dennis Gabor in 1949 where an imaging wave caused by diffraction at the sample plane interferes with a reference wave incoming from the non-diffracted light passing through the sample and the result is recorded by an electronic imaging device. DIHM has been the cornerstone of a new kind of holographic microscopes that have some advantages (such as pricing, compactness, dimensions and handling) regarding conventional holographic microscopes. Nevertheless, they still retain some disadvantages such as relatively modest numerical aperture, limited sample range applicability, noise, etc. It is the aim of our group to push on the development of new techniques capable of improving performance in lensless microscopy. . .
REMOTE MONITORING OF SOUND (OPTO-PHONE) AND BIOPARAMETERS USING SPECKLE METROLOGY: The ability of dynamic extraction of remote sounds is very appealing for a wide range of applications ranging from homeland security to sensational press. We have developed in collaboration with the group of Prof. Zeev Zalevsky from the Bar-Ilan University, a novel technology for remote estimation of the sound. It is based on the analysis of speckle patterns that are recorded with proper optics. Then, by digital image processing tools it is possible to translate the vibration/tilting profile of the surface under analysis into sound. Since the technology acts essentially as a transducer element that enhances the vibration profile of the surface being inspected, changes in the vibration profile can be traced by analyzing changes in the reflected speckle pattern. Thus, the technique is not only valid for speech analysis but also for identifying obscure or camouflaged objects, for tracking cells with nanometric accuracy, as well as for monitoring bio-parameters such as glucose level, heart rate, intra-ocular pressure, alcohol level in blood, etc. And it is possible (depending on the application) to adapt the proposed technology to a given application by using low cost components. . .
QUANTITATIVE PHASE AND 3D IMAGING: PHASE RETRIEVAL AND RANGE IMAGING: Three-dimensional (3D) quantitative imaging of micro- and macro-structures and their dynamics could find numerous applications in many fields such as 3D metrology, pre- and post-production control, object recognition, cell biology and medicine, just to cite a few. Inside of our group, we are interested in the development of new methods for quantitative phase and 3D imaging. We have been mainly focused to the fields of microscopy (quantitative phase imaging) and 3D mapping by remote sensing. Quantitative phase imaging in microscopy deals with the capability of phase retrieval by using interferometric or non-interferometric approaches. Since the phase distribution transmitted by a sample contains information of both the surface profile as well as the internal distribution of the sample (changes in the refractive index values), phase retrieval provides extremely useful information of the sample under test. 3D mapping and range measurement deals with the analysis of objects in the far field and permits 3D representation and object recognition based on the retrieved 3D information. . .
OPTHALMIC APPLICATIONS AND PHYSIOLOGICAL OPTICS: Ophthalmic developments are also covered by our group through a double research line. First, the development of novel ophthalmic instruments improving capabilities of existing ones concerning characterization/visualization/measurement of ophthalmic-related parameters is addressed inside our group. Those ophthalmic instruments can be based on emerging technologies and/or novel applications to the eye of well-known approaches in other research fields. Just as a couple of examples, we have reported on a new measurement device enabling high-precision, noncontact remote and repeatable IOP monitoring based on an innovative measurement principle (secondary speckle pattern tracking) and in a new ophthalmic instrument for visualization and characterization of engraved marks in progressive addition lenses (PAL) based on in-line holography. And second, the group also works in theoretical aspects on physiological and visual optics through the application of advanced mathematical formalisms (power vectors and dioptric power matrices) such as, for instance, astigmatic wavefront propagation, lateral magnification matrix in presence of astigmatism, refractive status prediction from biometric measurements, etc. . .
