- Single-pixel optical sensing architecture for compressive hyperspectral imaging Hoover Fabián Rueda-Chacón Cesar Augusto Vargas-García Henry Arguello-Fuentes Ingeniería Single based systems pixel detector coded aperture optical imaging Compressive hyperspectral imaging systems (CSI) capture the three- dimensional (3D) information of a scene by measuring two-dimensional (2D) coded projections in a Focal Plane Array (FPA). These projections are then exploited by means of an optimization algorithm to obtain an estimation of the underlying 3D information. The quality of the reconstructions is highly dependent on the resolution of the FPA detector, which cost grows exponentially with the resolution. High-resolution low-cost reconstructions are thus desirable. This paper proposes a Single Pixel Compressive Hyperspectral Imaging Sensor (SPHIS) to capture and reconstruct hyperspectral images. This optical architecture relies on the use of multiple snapshots of two time- varying coded apertures and a dispersive element. Several simulations with two different databases show promising results as the reliable reconstruction of a hyperspectral image can be achieved by using as few as just the 30% of its voxels. 2014 artículo científico 0120-6230 https://www.redalyc.org/articulo.oa?id=43032606012 en http://www.redalyc.org/revista.oa?id=430 Revista Facultad de Ingeniería Universidad de Antioquia application/pdf Universidad de Antioquia Revista Facultad de Ingeniería Universidad de Antioquia (Colombia) Num.73
