Abstract: The invention relates to a method for exposing at least one stored image (21) on a light-sensitive recording medium (14), with an exposure device (11), which picks up at least one recording medium (14) on a support (12), with at least one exposure head (16, 17), which is moved above the support (12) along a guiding axis (18) in the X direction and the guiding axis (18) and/or the support (12) are moved in the Y direction, with a control system, by which a traversing movement of the at least one exposure head (16, 17) is operated for exposing the at least one image (21) of the recording medium (14) and/or the recording medium (14), wherein the position of the recording medium (14) and/or the position of the at least one image (21) on the recording medium (14) are detected with at least one linear image acquisition device (25), which extends at least partially in the X direction.

Abstract: The computerised determination of the position of a measuring point M to be surveyed in three-dimensional space requires two reference points PI and PII with known space coordinates, a digital video camera with an image-capturing sensor and a computer with a screen. The camera is positioned at reference point PI. In this position, it can be rotated to two different alignment positions PI* and PI**. In the first of these rotation positions PI*, the screen shows (among other things) the depiction PII? of the second reference point PII lying at a distance and a number of marking points (P1?, P2?, PT, P4?, P5?, . . . ) which are marked by abrupt changes in the brightness profile of the image. In the second rotation position PI**, only certain marking points (P1?, P2?, P3?, . . . ) selected according to certain criteria are shown as well as the measuring point M to be surveyed.

Abstract: In a partial image, certain image dots are deflected optically in x direction with reference to imaginary undeflected image dots, and the x deflection of an image dot is less than the length of the side of an image dot. The image is traced by a light-controlling unit (preferably a semiconductor chip with tilting-mirror elements) with light-controlling elements arranged similar to a matrix. A computer program loads the light-controlling unit with a control pattern for tracing each partial image.

Abstract: The grid image T (overall image) is traced in dots by a computer program as a sequence of image sections (R1, R2, R3, R4, . . . ) on a tracing carrier (1) moving through an exposure station in direction v. All the dots in an image section are traced simultaneously. The image sections are traced at moments (t1, t2, t3, t4) of exposure to a flash light each of which takes place when the tracing carrier (1) has moved a distance (d) which is always equal. Successive images always partially overlap one another in such a way that the overlapping parts coincide with a section of the overall image being traced. The tracing is carried out by means of a light-controlling unit, preferably a semiconductor chip with tilting-mirror elements with light-controlling elements arranged similarly to a matrix. In order to trace each image section the light-controlling unit is loaded with the corresponding control pattern by a computer.

Abstract: Process and apparatus for a plotting raster image on a light-sensitive carrier. The process includes continuously displacing an exposure head, having a light modulator, relative to the light-sensitive record carrier, positioning a lens between the exposure head and the light-sensitive record carrier, and displacing the lens relative to the exposure head and light-sensitive record carrier. The apparatus includes an exposure head having a light modulator, a light-sensitive record carrier, and a plotting drive unit coupled to at least one of the exposure head and the light-sensitive record carrier. In this manner, the exposure head and the light-sensitive record carrier are adapted for relative movement to each other. The apparatus also includes a lens positioned between the exposure head and the light-sensitive record carrier, and a lens drive unit coupled to the lens. In this manner, the lens is adapted for movement relative to the exposure head and light-sensitive record carrier.

Abstract: Method and apparatus for plotting a raster image on a plane record carrier. A computer-stored raster image includes raster points and is convertable into controllable, raster-point related light beams in which picture elements corresponding to the raster points are plotted on the record carrier. The method includes dividing the computer raster image into matrix-like imaginary computer raster image subareas, dividing the raster image of the record carrier into matrix-like imaginary raster image subareas of the record carrier, and associating the subareas of the computer raster image and the subareas of the raster image of the record carrier with each other. The method further includes dividing the computer raster image subareas into n matrix-like imaginary raster point positions, dividing the raster image subareas of the record carrier into n matrix-like imaginary picture element positions, and associating the n matrix-like picture element positions with the n matrix-like raster point positions.
