Abstract
Instrumentation systems and optical techniques see increasingly becoming extremely useful tools in scientific and technological applications due to its precision and measurement speed. Particularly, holography is an interferometric-diffractive technique that allows the recording and reconstruction of 3D images of objects as a hologram carries the intensity and phase information of a 'holografado' object. Recently, increased processing and storage capability of personal computers and parallel processing hardware, the development of new devices optoelectronic as spatial modulating light (SLMs), the CMOS and CCD cameras (Coupled Charge Device) High resolution and new photochromic materials; It is enabling, respectively, the viability of computer generated holograms (CGH Computer Generate Hologram) and experimental implementation of holographic recording and optical systems and numerical reconstruction of three-dimensional objects and generation of special optical beams. On the other hand, non-diffractive beams has shown potential for many applications, because their non-scattering properties and are resistant to diffraction, where they can be experimentally generated via optical reconstruction of CGHs devices using SLMs or photorefractive holography. The aim of this research project is to study and develop instrumentation and optoelectronic systems based on holographic techniques and non-diffractive beam. Thus, in a first proposal we intend to develop a holographic optical-handling system of micro and nano particles based on non-diffractive beams. In a second proposal, we intend to study and mount an optical-holographic interferometry system based on non-diffractive beam and analyze its accuracy and functionality. In a third and final purpose of this project, we intend to study and develop a 3D projection system based on a matrix composed by the superposition of non-diffractive beam generated by co-axial superposition of Bessel beams, where each beam behave like a 3D pixel of image. All the foundations of the proposed systems are theoretically grounded and experimentally in work carried out by our group and others in the literature; well, have a high degree of originality and are at the frontier of knowledge in this area, as this instrument is not yet developed or consolidated with excellent project success prospects.
