Abstract: A process serves to record the deformation of objects (1). In order to facilitate reliable evaluation even in the case of relatively large deformations, during the deformation of the object (1) a sequence or series of images of the object is recorded with a measuring process. The differential between two sequential images is formed. These differentials are integrated (FIG. 1).

Abstract: In a method for determining the absolute coordinates of an object (1), the object (1) is exposed to light (3) through a projection grid (2). The light (4) reflected by the object 1 is registered by a sensor (5). The image picked up by the sensor is evaluated. In order to improve such a method, the projection grid (2) comprises a first grid with a first grid vector (G1), and a second grid with a second grid vector (G2) which differs from said first grid vector. The sensor (5) is arranged at a distance (b) from the projection grid (2) such that the projections (bx, by), of the base vector (b) leading from the first and from the second grids to the sensor (5), onto the associated grid vectors (G1, G2) differ in size.

Abstract: The invention serves for the contour measurement and/or deformation measurement of an object, particularly a tire or a structural component of a composite material. The object is irradiated with light, particularly structured light, that is emitted by a radiation source and consists, in particular, of coherent light or partially coherent light, especially laser light. The light reflected by the object is picked up by a camera with an imaging sensor. In order to improve the image quality, a first image is produced with a first adjustment of the camera and/or the radiation source which is adapted to a first image region (13). In addition, a second image is produced with a second adjustment of the camera and/or the radiation source which is adapted to a second image region (12). Both images are combined (FIG. 5).

Abstract: A method serves the direct phase-angle measurement of radiation, in particular of light radiation which is reflected from a body. The body is exposed to coherent radiation. The radiation reflected from the body is imaged by an imaging optical system (6) in an image plane in which a sensor is located. A reference radiation generated in accordance with the shearing method is superimposed on the sensor. The phase of the radiation from the body is determined from the measurement signals of the sensor. To improve such a method, the imaging optical system (6) possesses a diaphragm (11) having one or two apertures (12, 13) (FIG. 2a).

Abstract: A fibre-optic laryngoscope spatula (1) having a light-exiting first end and an opposite second end and comprising a base part (1) and an exchangeable light-guide part (8) having a first spring-loaded coupling member (14). The base part (1) and the light-guide part (8) are designed to fit precisely together in such a way that the light-guide part (1) can be pushed into the base part (1) from the second end as far as an end position and can be pushed out of the base part (1) from the end position in the opposite direction. When in the end position, the light-guide part (8) and the base part (1) are connected to one another by means of a snap connection and have interengaging surface parts which do not allow relative movement between the base part and light-guide part in any other than the push-out direction. Furthermore, when in the end position, at least one snap connection force has to be overcome in order to allow relative movement between the base part (1) and light-guide part (8) in the push-out direction.

Each of the external mirrors serves as an image splitter for dividing the light into two distinct optical observation paths. The first optical observation path is used to produce a stereoscopic image of the eye suitable for binocular viewing. The second optical observation path is used to produce a non-stereoscopic image of the eye suitable for monocular or binocular viewing.
