Abstract:
An instrument for imaging a specimen or a portion of a specimen is configured to capture multiple image frames of the portion of the specimen being scanned using Moving Specimen Image Average (MSIA) to create one or more image strips. The instrument is configured to use an active area of a two dimensional sensor array that covers substantially all of the width of the sensor array but less than a length. The one or more image strips are created from the multiple image frames as each of the multiple image frames is captured. Preferably, the instrument is configured to remove blurring, caused by distortion of the optics, by software or by warping a grid of the two dimensional detector array, including TDI array.

Abstract:
A viewing apparatus for producing a stereoscopic image for an observer, the viewing apparatus comprising : first and second video projectors for projecting respective ones of first and second video images of an object, the first and second images being different images which are one or both of spatially and angularly shifted in relation to the object so as to convey parallax between the images; a mirror arrangement comprising a concave mirror which receives light from the first and second video projectors, the mirror arrangement being located in relation to the first and second video projectors such that focussed images of the object are produced at the mirror arrangement; and a viewing lens for relaying exit pupils corresponding to each of the focussed images as reflected by the mirror arrangement to a viewing plane so as to be viewable at the respective eyes of the observer as a stereoscopic image without use of adapted eyewear; wherein the video projectors comprise first and second video displays which are driven by first and second video signals to display respective ones of the first and second video images, and first and second optical arrangements for focussing light from the respective images as displayed by the first and second displays to the mirror arrangement.
Abstract:
Die vorliegende Erfindung betrifft eine Aufnahmevorrichtung zur Abbildung eines Objektes. Die Aufnahmevorrichtung (1) umfasst eine Aufnahmeeinheit (11). Das Objekt wird im Wesentlichen auf zwei optischen Pfaden (111, 112) mit jeweils einem Winkel (α, ß) zu einer optischen Achse (10) abgebildet. Jedem optischen Pfad (111, 112) ist eine Bildebene (110) zugeordnet. Die Bildebene (110) weist vorzugsweise ein oder mehrere lichtempfindliche Elemente (112) auf. Die Winkel (α, ß) der optischen Pfade sind zur optischen Achse (10) einstellbar.
Abstract:
The present invention relates to digital pathology, and relates in particular to a digital pathology scanner illumination unit. In order to provide digital pathology scanning with improved illumination, a digital pathology scanner illumination unit (10) is provided that comprises a light source (12), a light mixing chamber (14), and a light diffuser (16). The light source comprises a plurality of light elements (18) that are arranged longitudinally along a linear extension direction. The mixing chamber comprises a transparent volume (22) providing a mixing distance (DM) between the plurality of the light elements and the light diffuser such that light with a uniform intensity is provided at a downstream edge (26) of the mixing chamber; and the mixing chamber is arranged, in terms of light propagation, between the plurality of the light elements and the light diffuser. Further, the light diffuser comprises a diffusing material such that the light is transformed into light that has uniformity at different angles, in particular low angles.
Abstract:
The present disclosure relates to an improved optical arrangement for an optical imaging system or the like, comprising: an optical device; a digital micromirror device having a plurality of individually addressable micromirrors; a convex mirror; and a concave mirror concentric to the convex mirror. The convex mirror and the concave mirror define an optical triplet which is located in an optical path with the digital micromirror device and the optical device. The concave mirror comprises two concave mirror sections, one or both concave mirror sections being moveable relative to the convex mirror so as to control an image mapping between the digital micromirror device and the optical device.

Abstract:
The present invention concerns a device for three-dimensional viewing and image projection. One of the main applications of this invention is the design of microscopes for viewing three-dimensional objects magnified to a high degree. A known projection lens (2) reflects on a double-sided mirror screen (5) the image of an object (1) illuminated through a slit diaphragm (3). Said mirror screen rotates around an axis (YY'), enabling the observer (8) to see the tridimensional image (6) in its inherent colour through a Fresnel-type lens-screen (7). A focussing correction lens (4) serves to correct the optical distortions created by the mirror and to collimate said image.
