In Summer 2007, we field-tested a robotic survey system at Haughton Crater (Devon Island, Canada). Two NASA Ames K10 planetary rovers performed systematic surveys of several simulated lunar sites, including a roughly 700m x 700m region called Drill Hill. The rovers carried a 3D scanning lidar for topographic mapping and ground penetrating radar to map subsurface structure. In this paper, we des...
Abstract This contribution presents an elastohydrodynamic lubrication (EHL) model for pneumatic spool valves. For accurate estimation of the transient friction this tribological sealing system, surface topography cylindrical counterfaces valve housings are measured and analyzed with optical measurement instrument. Based on data, properties flow factors system derived. It has been found that con...
This paper is intended to give an overview on current surveying techniques that use remotely sensed data, and their applications in archaeology. The focus is on optical 3D measurement techniques based on image and range sensors. Data and methods are briefly reviewed, whereas data processing and related problems are only touched on in passing. For the purpose of this review we distinguish three ...

Fluorescence imaging is a powerful technique with diverse applications in intraoperative settings. Visualization of three dimensional (3D) structures and depth assessment of lesions, however, are oftentimes limited in planar fluorescence imaging systems. In this study, a novel Fluorescence Imaging Topography Scanning (FITS) system has been developed, which offers color reflectance imaging, fluo...
