Abstract: L'invention concerne un procédé d'observation d'un échantillon, en particulier une lame d'anatomo-pathologie, formée à partir d'une fine épaisseur d'un tissu biologique prélevé. Il comporte une étape d'illumination de l'échantillon par une source de lumière et l'acquisition, par un capteur d'image, d'une image représentant la lumière transmise par l'échantillon. L'image fait l'objet d'une reconstruction holographique, de manière à obtenir une représentation, dans le plan de l'échantillon, de l'onde lumineuse transmise par ce dernier. Le procédé comporte l'application d'un fluide dit d'imprégnation sur l'échantillon, de telle sorte que l'échantillon s'imprègne dudit liquide d'imprégnation, ledit liquide d'imprégnation ayant un indice de réfraction strictement supérieur à 1.

Abstract: Die Bestimmung des Phasenüberganges eines in einem Gasstrom befindlichen Multikomponententropfens, in dem kristalline Feststoffe gelöst sind, in einen festen Zustand erfolgt mittels einer Streulichtdetektion, bei der die auf eine bestimmte Temperatur erwärmten Flüssigkeitstropfen zur Detektierung ihrer Interferenzmuster durch einen Laserstrahl geführt werden. Die Detektierung der Interferenzmuster erfolgt dabei mittels eines auf die Laserlichffrequenz abgestimmten CCD-Arrays oder eines Photopapiers. Bei einer detektierten signifikanten Interferenzmusteränderung bei einer gleichen Tröpfchengröße aber bei unterschiedlichen Tröpfchentemperaturen erfolgt der Phasenübergang der flüssigen Tröpfchen in einen festen Zustand.

Abstract: Das beschriebene Verfahren zur Bestimmung lokaler Strukturen in optischen Materialien, wie z.B. Kristallen, umfaßt einen ersten Schritt der visuellen Bestimmung von Defekten, z.B in Form sichtbarer Schlieren, im Material, einen zweiten Schritt bei dem von lokalen Schlieren und Materialfehlern mit einer Ortsauflösung von mindestens 0,5 mm die Spannungsdoppelbrechung bestimmt wird, und einen dritten Schritt, bei dem Materialfehler mit derselben Ortsauflösung von 0,5 mm mittels Interferometrie bestimmt werden. Das Verfahren ist zur Herstellung optischer Elemente, insbesondere für die Mikrolithographie geeignet.

Abstract: A method of forming a shadowgraph image is described, comprising the steps of illuminating a glazing (52), e.g., a vehicle windscreen, with light from a localised light source (50), said light being expanded and collimated by a lens optical system (54) or a mirror optical system; forming a virtual shadowgraph image of the glazing in a virtual image plane (56), which may be positioned behind or in front of the glazing; and imaging the virtual image onto a CCD camera (62). The glazing may be moving relative to the light source or may be stationary. Furthermore, a method of glazing inspection is described, comprising forming a shadowgraph image as outlined above; processing the shadowgraph image to exclude measurement points corresponding to obscure areas of the glazing as non-valid measurement points; obtaining a processed image by determining an illumination value for each valid measurement point; constructing a reference image by scanning a convolution window point by point over the processed image; and comparing the illumination value of the corresponding point of the reference image.

Abstract: A method of determining the optical quality of a glazing which includes at least one area having a reduced light transmission, wherein a shadowgraph image of the glazing is produced and the illumination of the glazing is measured at a plurality of measurement points arranged in an array extending over the glazing. The deviation in illumination form a desired value at each measurement point is determined and wherein the at least one area of reduced light transmission is omitted from the array of measurement points.

Abstract: Method and apparatus for detecting conditions in the atmosphere which are hazardous to flying aircraft and providing early warning to pilots or ground personnel. The method includes using a laser beam and a coherent optical receiver to optically sense sound waves produced by those hazardous conditions and measuring the effect of those sound waves on the transmitted and received optical beams.

Abstract: A process for detecting striae in a sample (13) is provided which includes the steps of: 1) preparing a digitized phase plot (fig. 3) for the sample using an interferometer (15, 19, 21, 23, 25, 27, 29); 2) applying a high pass filter to the phase plot to remove the effects of the sample's bulk properties (fig. 6); 3) applying a statistical filter to the high pass filtered data to remove outlying data points (fig. 8); 4) column averaging the statistically filtered data (fig. 10).
