    Analysis of optomechanicalMethod for materials selection in optical design
    (OSA - The Optical Society, 2016-01-01) Cano-Barrera, C.; Restrepo, R.; Zuluaga-Ramírez, P.; Universidad EAFIT. Departamento de Ciencias Básicas; Óptica Aplicada
    We present a technique to determine the wavefront error and polarization changes introduced by a loaded optical material based on its optical, thermal and mechanical properties through an integrated optomechanical simulation process. © OSA 2016.

    Design considerations of HUD projection systems applied to automobile industry
    (SPIE Press, 2012-04-26) Betancur, J. Alejandro; Gómez, G.O.; Betancur, J. Alejandro; Gómez, G.O.; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ingeniería de Diseño (GRID)
    Currently, the topics about HUD systems are strongly going inside on the automobile industries; consequently, there have been proposed new ways to understand and apply this technology in an economically viable way.

    Design of a linear in wavenumber spectrometer
    (OSA - The Optical Society, 2018-01-01) Ruiz-Lopera S.; Restrepo R.; Universidad EAFIT. Departamento de Ciencias Básicas; Óptica Aplicada
    We describe the optical design of a linear in wavenumber spectrometer that combines a grating and a prism. OpticStudio software was used to validate the performance of the design. High lineartiy in k-space was achived. © 2018 The Author (s)

    Integration of head-up display system in automotive industry: A generalized application
    (SPIE-INT SOC OPTICAL ENGINEERING, 2013-01-01) Alejandro Betancur, J.; Osorio, Gilberto; Mejia, Alejandro; Alejandro Betancur, J.; Osorio, Gilberto; Mejia, Alejandro; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecánica Aplicada
    Throughout the development of the automotive industry, supporting activities related with driving has been material of analysis and experimentation, always seeking new ways to achieve greater safety for the driver and passengers. With the purpose of contributing to this topic, in order to contribute to this subject, this paper summarizes from past research experiences the use of Head-Up Display systems applied to the automobile industry, covering it from two main points of discussion: the first one, from a technical point of view, in which the main principles of optical design associated with a moderate-cost experimental set up are brought out; and the second one, an operational approach where an applied driving graphical interface is presented. Up to now, the results suggest that the experimental set up here discussed could be adaptable to any automobile vehicle, but it is needed further research and investment.

    Status of the EMIR mechanical system
    (SPIE-INT SOC OPTICAL ENGINEERING, 2006-06-28) Sánchez, V.; Barrera, S.; Becerril, S.; Correa, S.; Pérez, J.; Redondo, P.; Restrepo, R.; Saavedra, P.; Tenegi, F.; Patrón, J.; Garzón, F.; Universidad EAFIT. Departamento de Ciencias Básicas; Óptica Aplicada
    EMIR is the NIR multi-object imager and spectrograph for the GTC (Gran Telescopic Canarias). The instrument ADR (Advanced Design Review) was held successfully in March 2006. During the AD phase, a number of mechanical concepts were tested on development prototypes to ensure the feasibility of the PDR proposed designs. This presentation contains an overview of the current mechanical status of the instrument, as well as the prototypes development. It contains the prototype tests results of the collimator first lens barrel, the support trusses, the grisms wheel and the demonstration programme for the cryogenic reconfigurable slit mechanism.
