Abstract:
A method and system for beam shaping employing a non-collinear quasi phase-matched interaction in a crystal whose nonlinear coefficient was encoded by a computer generated hologram is provided herein. The same axis is used for both satisfying the phase-matching requirements and encoding the holographic information. This allows one-dimensional beam shaping using a very simple to fabricate nonlinear crystal pattern and two-dimensional beam shaping with high conversion efficiency. Both are demonstrated by converting a fundamental Gaussian beam into Hermite-Gaussian and Laguerre-Gaussian beams at the second harmonic in KTiOPO 4 and stoichiometric lithium tantalate. The suggested scheme enables broad wavelength tuning by simply tilting the crystal.
Abstract:
A direct-write lithography apparatus includes a polarization selector stage configured to vary a polarization orientation angle of light from a light source, a focusing element configured to focus the light from the light source into a spot at a focal plane thereof, and a scanning stage configured to scan the spot in at least two dimensions along a surface of a polarization-sensitive recording medium that is arranged proximate to the focal plane such that neighboring scans substantially overlap. The polarization selector stage and the scanning stage are configured to be operated independently of one another. Related fabrication methods of and optical elements fabricated thereby are also discussed.
Abstract:
This invention relates to digital holographic microscopy for analyzing a sample comprising at least one translucent biological object. A disclosed apparatus comprises at least one light source arranged to create at least one beam of coherent light, the at least one beam comprising at least one object beam, a sensor, a beam directing means arranged to direct said at least one beam, and a sample holder adapted to hold the sample. The sample holder comprises a first reflecting surface which in use is arranged below the sample. The first reflecting surface is essentially flat and is arranged to reflect the at least one object beam. The light source, the beam directing means and the sample holder are arranged relatively each other such that the at least one object beam is directed towards the first reflecting surface at an angle which is essentially perpendicular to the first reflecting surface, and such that the at least one object beam that has passed through the sample is directed towards the sensor. The disclosed invention may be used to achieve a better signal-to-noise ratio when analyzing translucent biological objects by means of digital holography.
Abstract:
A display device for displaying 3D holographic images has multiple pixels, each having a set of coupled optical resonators. The optical paths of the coupled optical resonators can be adjusted to impart a desired phase shift to light passing through the coupled optical resonators. The transmission amplitude and phase of each pixel of the display can be dynamically and individually adjusted for displaying 3D holographic images

Abstract:
This invention relates to holographic image display systems (200), and to related methods and processor control code. We describe a method of displaying an image holographically, the method comprising: inputting display image data defining said image for display; processing said image data to determine first image data representing a first spatial frequency portion of said image data and second image data (206) representing a second spatial frequency portion of said image data, wherein said second spatial frequency is higher than said first spatial frequency; displaying a hologram (204) of said first image data on a spatial light modulator (SLM1) to form a holographically-generated intermediate real image; onto a second spatial light modulator (SLM2) which modulates the intensity of said intermediate real image using said second image data (206) to display said image.
