3 p, 290.0 KB Evaluation and correction of aberrations in an optical correlator by phase-shifting interferometry / Iemmi, Claudio (Universidad de Buenos Aires. Departamento de Fisica) ; Moreno Soriano, Alfonso (Universitat Autònoma de Barcelona. Departament de Física) ; Nicolás Román, José (Universitat Autònoma de Barcelona. Departament de Física) ; Campos Coloma, Juan (Universitat Autònoma de Barcelona. Departament de Física)
We propose a new method for evaluating and correcting aberrations in a Vander Lugt correlator. The technique is achieved with liquid-crystal displays of the correlator and allows the task to be performed in situ. [...]

En aquesta tesi es proposa i estudia una arquitectura per al reconeixement òptic a temps real d'imatges en color. Aquest estudi es divideix en tres parts principals. La primera és la definició d'un formalisme per a descriure les imatges en color mitjançant funcions tridimensionals, entre les que una conté la distribució de color de cada píxel. [...]
In this thesis a new architecture for real time color pattern recognition is proposed and studied. This study is divided in three main parts: First, the definition of a formalism to describe color images by three dimensional functions, in which the third variable contains the color distribution of each pixel. [...]
