1. DUAL BEAM HETERODYNE FOURIER DOMAIN OPTICAL COHERENCE TOMOGRAPHY (WO 2008/087613)

   wipo.int (Jul 24 2008) Patents Explore Article

   The present invention relates to an apparatus and a method combining achromatic complex FDOCT signal reconstruction with a common path and dual beam configuration. The complex signal reconstruction allows resolving the complex ambiguity of the Fourier transform and to enhance the achievable depth range by a factor of two. The dual beam configuration shares the property of high phase stability with common path FDOCT. This is of importance for a ... (Read Full Article)

2. Microscopy imaging apparatus and method for generating an image

   PatFT » Page 1 of 1 (Jun 10 2008) Microscopy , Patents Explore Article

   A method and a microscopy imaging apparatus for generating an optically sectioned image of a specimen are provided. The method comprises the steps of: illuminating the specimen with a modulating, spatially periodic illumination pattern; imaging said specimen on a conjugate image plane; acquiring a plurality of signals at respective positions on said image plane, each signal corresponding to the incident light intensity at that position and having an oscillatory component ...

3. Fast focus field calculations

   SPIE Digital Library (Feb 12 2008) Microscopy Explore Article

   Marcel Leutenegger, Matthias Geissbuehler, Iwan Marki et al. We present a method for fast calculation of the electromagnetic field near the focus of an objective with a high numerical aperture (NA). Instead of direct integration, the vectorial Debye diffraction integral is evaluated with the fast Fourier transform for calculating the electromagnetic field in ... [Proc. SPIE Int. Soc. Opt. Eng. 6861, 68610R (2008)] published Tue Feb 12, 2008. (Read Full Article)

4. Method and apparatus for fixing a location

   PatFT » Page 1 of 1 (May 25 2004) Patents Explore Article

   A method is disclosed for fixing at least one location in an examination field (9) with respect to a coordinate system (13). The method includes determining, in response to a request (65), coordinates of a first location (59) as a first coordinate set (x, y, z) allocated to the first location (59). A first recording and a second recording of topological data (69) in a spatially extended area around the ... (Read Full Article)
