Abstract:
Um eine verbesserte Projektion bei Projektionssystemen bereitzustellen, bei welchen zumindest zwei Projektionen auf der Projektionsfläche in vorgegebener Weise relativ zueinander angeordnet sind, wird eine optische Korrektureinrichtung vorgeschlagen. Diese ist für ein Projektionssystem vorgesehen, welches zumindest einen Projektor aufweist, der Bilder auf eine Projektionsfläche projiziert, wobei jeweils zumindest zwei Projektionen auf der Projektionsfläche in vorgegebener Weise relativ zueinander angeordnet sind, um einen vorgegebenen Bildeindruck zu erzeugen. Die erfindungsgemäße Korrektureinrichtung zeichnet sich dadurch aus, dass sie zwei beabstandete transparente Platten umfasst, deren Abstand zueinander einstellbar ist, wobei die Korrektureinrichtung im Strahlengang zumindest einer Projektion des Projektionssystems anordenbar ist. Durch diese Gestaltung der erfindungsgemäßen optischen Korrektureinrichtung wird ein einfaches Mittel bereitgestellt, um durch Abbildungsfehler hervorgerufene geometrische Ungenauigkeiten in der Überlagerung von mehreren Projektionen auszugleichen, sodass die projizierten Bilder oder Bildteile deckungsgleich überlagert werden können.
Abstract:
A method for manufacturing an optical component includes mounting each, of a series of replicating inserts to a movable support such as a mold slide. Each of the replicating inserts defines a replicating surface that bears micro-optical structures. Each of the supports is moved relative to one another so that the replicating surfaces of the inserts form at bast portions of surfaces of a concave geometric shape. An optically transmissive substrate is then disposed between the replicating surfaces, so that the micro-optical structures of the replicating surfaces are impressed upon externally facing surfaces of the optically transmissive substrate. Each of the mold slides are then moved away from the externally facing surfaces of the optically transmissive substrate, in a direction that is selected to preserve the impressed micro-optical structures.
Abstract:
The invention relates to an optical multiple circuit breaker with (N) first optical inputs (E1 (n)), whereby these inputs can be switched optionally to (N) first or (N) second optical outputs (A1(n)) and/or (A2(n)). Light rays (LS1(n)) and LS2(n)) are reflected or transmitted from two surfaces (27, 28), to which end the at most two recesses (25) of a transparent base body (1) that form these surfaces are filled optionally with an optically thinner or denser material (26). In accordance with a first embodiment, both surfaces (27, 28) are so arranged that, in the reflecting switching state, the first inputs (E1(n)) are optically connected to the first outputs (A1(n)), and the second inputs (E2(n)) are connected to the second outputs (A2(n)), and that in the transmission switching state, the first inputs (E1(n)) are optically connected to the second outputs (A2(n)). Owing to low optical damping and compact structure, the above-described optical multiple circuit breakers can be used advantageously in optical communication engineering, in particular in the realization of optical bus systems.

Abstract:
Die Erfindung betrifft eine richtungsgesteuerte Beleuchtungseinheit, die Licht von aktivierten Beleuchtungselementen durch ein transmissives Bildwiedergabemittel in Sichtbarkeitsbereiche ablenkt. Die Sichtbarkeitsbereiche werden mit einer Nachführeinrichtungs- und Bildsteuerung den Augen verschiedener Betrachter zu anderen Positionen vor dem Display nachgeführt. Um eine strenge Zuordnung eines Bildpunktes der Bildwiedergabemittel (6) mit einem Ablenkelement (Elektro-Benetzungszelle) eines Ablenkmittels zu vermeiden, enthält die richtungsgesteuerte Beleuchtungseinheit vor dem Bildwiedergabemittel im Lichtweg seriell angeordnete fiächenhafte Beleuchtungsmittel (1), die für die Bildwiedergabemittel homogenes Licht bereitstellen, und Ablenkmittel (3), die mindestens ein Feld mit einer Anordnung von Elektro-Benetzungszellen enthalten, die von der Nachführeinrichtungs- und Bildsteuerung (10) mindestens in Gruppen diskret adressierbar und im Brechungsverhalten einstellbar sind und eine steuerbare Prismenfunktion realisieren, um die Strahlenbündel sequentiell und synchron zu den alternierend modulierten Strahlenbündeln auf die dem aktuell modulierten stereoskopischen Bild zugeordnete Augenposition auszurichten, und zusätzlich eine steuerbare Linsenfunktion realisieren, um die Sichtbarkeitsbereiche abhängig von der Entfernung der Betrachteraugen von den Bildwiedergabemitteln anzupassen.
