Abstract: Autofocus system (AF) employing, in addition to specified optical units, fringe projection and fringe detection systems (FPS, FDS) and specifically-configured data processing system. AFS is configured to project with FPS a sinusoidal fringe pattern, formed by a pattern source, on a substrate and to image the so projected pattern from substrate onto optical detector with FDS to form optical image from which topology of the substrate is defined as substrate moves relative to the projected pattern. Pattern source may include diffraction grating oriented that the projected pattern is inclined relative to direction of substrate scanning Topology profile is corrected for tilt of substrate, Goos-Hanchen errors, and for fringe-pattern-induced errors outside a chosen spatial-frequency range. To reduce errors of topology profile, at least five values of phase difference are used. AFS is configured to define temporal phase shifting in optical image without using any moving parts in the AFS.

Abstract: Fringe-projection autofocus system devoid of a reference mirror. Contributions to error in determination of a target surface profile caused by air non-uniformities measured based on multiple measurements of the target surface performed at different wavelengths, and/or angles of incidence, and/or grating pitches and subtracted from the measured profile, rendering the system substantially insensitive to presence of air turbulence. Same optical beams forming a fringe irradiance pattern on target surface are used for measurement of the surface profile and reduction of measurement error by the amount attributed to air turbulence.

Abstract: Two dimensional encoder system and method designed to improve accuracy, compactness, stability, resolution, and/or light efficiency of metrology carried out with such system and method.

Abstract: An integrated optical assembly is provided, with enhancements that are particularly useful when the integrated optical assembly forms part of a laser radar system. The integrated optical assembly produces a reference beam that is related to the optical characteristics of a scanning reflector, or to changes in position or orientation of the scanning reflector relative to a source. Thus, if the scanning reflector orientation were to shift from its intended orientation (due e.g. to thermal expansion) or if characteristics of the scanning reflector (e.g. the index of refraction of the scanning reflector) were to change on account of temperature changes, the reference beam can be used to provide data that can be used to account for such changes. In addition, if the scanning reflector were to be positioned in an orientation other than the orientation desired, the reference beam can be used in identifying and correcting that positioning.

Moreover, the first substrate location (33A) is spaced apart from the second substrate location (33B). With this design, the first pattern beam (34A) can be transferred to the first substrate (14A) and the second pattern beam (34B) can be simultaneously transferred to the second substrate (14B).

Abstract: A pivoting dump rack for an existing pickup truck. The pivoting dump rack is mounted on pivot mounts with a single axis above the tailgate end of an existing pickup truck bed. On each rail of the pickup truck bed a hydraulic lift is mounted on a support frame. The hydraulic lifts raise the rack while the support frame distributes the load on the hydraulic lifts as they are in use. The rack is long enough to extend from the tailgate to above the cab of the pickup truck while providing extensions mounted on each end of the rack to further lengthen the pivoting rack and to increase the length of loads that can be carried by the pivoting rack. An attachable dump bed may also be fitted on the pivoting rack to allow it to carry loose items such as dirt and construction debris.

Abstract: A contrasting surface surrounding the pin minor when measuring aberrations of a lithographic projection system. By using a surrounding surface having a different reflectivity characteristic relative to the pin minor, the reflected wave front contains predominately single-pass aberration content because the amount of double-pass content is significantly reduced. As a result, the aberration measurement performed by a measurement system is more accurate.
