Abstract: A hyperspectral imaging device and method disclosed herein overcomes the technical problems associated with the prior art by replacing the intensity measurement performed by the single high-resolution 2D sensor of state-of-the-art methodologies, with the measurement of intensity (fluctuation) correlations retrieved by two high-resolution 2D sensors: one—the imaging/spatial sensor dedicated to polychromatic image acquisition, the other—the spectral sensor dedicated to pure spectral measurement. In the hyperspectral correlation imaging disclosed herein, the spectral information is encoded into the intensity correlation without requiring any spectral scanning. Even though multiple exposures (frames) are generally required to reconstruct light statistics and perform correlation measurements, the exposure times are several orders of magnitude shorter than those required in the scanning approach.

Abstract: An implant includes a cannula. The cannula defines an axial drainage bore and a plurality of radial openings providing a path of fluid communication between an exterior of the cannula and the axial drainage bore to drain fluid. The implant also includes a first sensor positioned at least partially in the cannula. The first sensor is configured to measure a biomarker in the fluid. The implant also includes a second sensor positioned at least partially in the cannula. The second sensor is configured to measure a pressure of the fluid. The implant also includes a third sensor positioned at least partially in the cannula. The third sensor is configured to measure a temperature of the fluid.

Abstract: A process and an apparatus for the plenoptic capture of photographic or cinematographic images of an object or a 3D scene (10) of interest are based on a correlated light emitting source and correlation measurement, along the line of “Correlation Plenoptic Imaging” (CPI). A first image sensor (Da) and a second image sensor (Db) detect images along a path of a first light beam (a) and a second light beam (b), respectively. A processing unit (100) of the intensities detected by the synchronized image sensors (Da, Db) is configured to retrieve the propagation direction of light by measuring spatio-temporal correlations between light intensities detected in the image planes of at least two arbitrary planes (P?, P?; D?b, D?a) chosen in the vicinity of the object or within the 3D scene (10).
