Evaluation of phase retrieval in a compressive computational ghost imaging setup
Ghost imaging has been developed into different setups to use the correlation properties of light to obtain the image of an object. Its computational version has been combined with Compressive Sensing algorithms to recover images with far less data than the Nyquist limit dictates. However, the retri...

La versión computacional se ha combinado con algoritmos de muestreo compresivo para recuperar imágenes con cantidades de datos mucho menores a la requerida por el límite de Nyquist. Sin embargo, la recuperación en la imagen de ciertas propiedades del objeto, como su espectro de fase de Fourier, no se ha estudiado usando montajes de Ghost Imaging. Esta monografía presenta este tipo de estudio. Específicamente, un nuevo montaje para Ghost Imaging computacional compresivo se presenta, y se implementa en la mesa óptica, obteniendo imágenes de alta calidad. Adicionalmente se propone, explica e implementa un procedimiento para medir indirectamente y cuantificar la recuperación de fase. Este procedimiento permite confirmar la recuperación exitosa de la información del espectro de fase a través de métodos de muestreo compresivo en un montaje de Ghost Imaging computacional.FísicoPregrado54 hojasapplication/pdfengUniversidad de los AndesFísicaFacultad de CienciasDepartamento de FísicaEvaluation of phase retrieval in a compressive computational ghost imaging setupTrabajo de grado - Pregradoinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/acceptedVersionhttp://purl.org/coar/resource_type/c_7a1fTexthttp://purl.org/redcol/resource_type/TPComputadores cuánticosProcesamiento de imágenes201327824Publicationhttps://scholar.google.es/citations?user=7Fa-MFYAAAAJvirtual::11260-10000-0002-7476-6119virtual::11260-1https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001337192virtual::11260-1e676d910-c320-4862-b7d4-2d8cc27eea1bvirtual::11260-1e676d910-c320-4862-b7d4-2d8cc27eea1bvirtual::11260-1ORIGINAL12234.pdfapplication/pdf2894947https://repositorio.uniandes.edu.co/bitstreams/972b205d-9844-4044-b95a-14462b56f934/downloadc8e09cd89d05e8c5caaf6750b8245e73MD51THUMBNAIL12234.pdf.jpg12234.pdf.jpgIM Thumbnailimage/jpeg6789https://repositorio.uniandes.edu.co/bitstreams/afa75298-5480-4af6-936b-0e26b2994b62/downloadc12c44a0c24185efc57bddbf9cac3a20MD53TEXT12234.pdf.txt12234.pdf.txtExtracted texttext/plain84045https://repositorio.uniandes.edu.co/bitstreams/46c867dd-4575-465e-954d-37e80ee14800/download40da18972a4c389fd9b4f96df288ea67MD521992/61308oai:repositorio.uniandes.edu.co:1992/613082024-03-13 14:23:23.974http://creativecommons.org/licenses/by-nc-sa/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co |

However, the retrieval in the image of certain properties of the object, such as its Fourier phase spectrum, has not been studied using ghost imaging setups. This monograph precisely presents this type of studies. Specifically, a new compressive computational ghost imaging setup is introduced, and implemented in the optical table, obtaining high quality images. Additionally, a procedure to indirectly measure and quantify the phase retrieval is proposed, explained and implemented. This procedure allows to confirm the successful recovery of phase spectrum information through compressive sensing methods in computational ghost imaging. |
