Abstract: The invention relates to the field of surface waves based optical devices particularly tuneable optical filter, optical biosensors and spatial light modulators. An optical sensor and tuneable filter is disclosed based on high contrast periodic structures deposited on a substrate and using a compact reading method for low detection limit using a one dimensionally diverging quasi-monochromatic beam and a camera.

Abstract: The invention is a SPR sensor that comprises a multi-layered plasmonic structure on a substrate for sensing. The SPR sensor has an enhanced figure of merit and lower limit of detection (system noise divided by the sensitivity) by at least two orders of magnitude than prior art SPR sensors. The plasmonic structure of the invention comprises a Nanostructured Porous Metal Layer (NPML) and at least one of: (a) buried dielectric layer under the nano-porous metal layer; (b) a nano-dimensional high index layer on top of the metal layer; and (c) a molecular layer for bio-functionalization adjacent to an analyte layer. The invention also encompasses many embodiments of measuring systems that comprise the SPR sensors of the invention with improved signal to noise ratio.

Abstract: A system microscopy system and method that enable obtaining high resolution 3D images in a single shot are presented. The system is an ultra-high speed, real time multi wavelength phase shift interference microscopy system that uses three synchronized color CCD cameras. Each CCD is equipped with a precision achromatic phase mask which in turn allows obtaining π/2 phase shifted signals in three different wavelengths simultaneously.
