Abstract: A method for analyzing a laser system, which has a focused laser beam and a controllable deflection assembly for controlling the transverse and/or longitudinal position of the beam focus, said method comprising the steps of directing the laser beam or a partial beam branched therefrom downstream of the deflection assembly toward an optically nonlinear medium for the purpose of generating frequency multiplied radiation, the wavelength of which corresponds to an uneven higher harmonic of the wavelength of the laser beam, activating the deflection assembly, and measuring a power of the frequency multiplied radiation while the deflection assembly is activated. The conversion efficiency of the nonlinear process by which the frequency multiplied radiation is produced is dependent upon the focusability of the laser beam. By evaluating the measured power of the frequency multiplied radiation, dynamic impairments of focusability can be detected, which can be caused by inertia-induced deformations of optical scan components of the laser system.

Abstract: A device and method for subaperture stray light detection and diagnosis in an optical system. A test light beam is generated with a width whose cross sectional area is less than the cross sectional area of a system aperture. Stray light is detected at a system detection surface. Based on the stray light and the location and direction angles of the light beam, potential paths that light may have taken to arrive at the detection surface are determined so as to identify physical features of the optical system that may have produced the stray light. A testing device comprises a test light beam source, preferably including a beam width magnifier, whereby the cross sectional area of the test light beam is made less than the cross sectional area of the system aperture. A relative lateral positioning stage and an angular beam directing stage launch the test light beam into the aperture at a selected position and selected directional angles. A detector and a data processing system produce a data set relating the stray light to the location and directional angles of the test light beam. A light trap and complementary test light beam delivery system are also provided.

Abstract: A method for determining the properties of surfaces wherein a first process step specified radiation emits from at least one radiation source to a measuring surface, in further process steps the radiation reflected and/or scattered off the measuring surface is detected by a plurality of image-capturing components, and a signal is generated which specifies at least one parameter of the radiation detected by the image-capturing components. In further process steps the first signals are grouped based on predetermined criteria to form group signals, and at least one group-specific evaluation figure is computed, and a dependent statistical parameter correlating with at least one measuring surface remission characteristic. Finally at least one statistical parameter is read out in dependence on the predetermined criterion for grouping said first signals. The properties of the surface are specified by a relation between at least two statistical parameters.

Abstract: A method and apparatus for calibrating a measurement system are provided. The method and apparatus compensate not only for lamp variations, but also for camera and optics variations. The system can be readily implemented and can be ported from one measurement system to another. One embodiment of the improved calibration system addresses the issue of variations between light sources by employing an automated lamp calibration system. One method calibrates existing or new lamps to match an established standard. In a preferred embodiment, the method will generate a reference table, for a measurement system defined as the standard, to act as the reference for all measurement systems. The reference table may be in the form of a data file that may be subsequently copied to other measurement systems. The reference table can then act as a global standard for other measurement systems, including future systems not yet made.
