Dual-Beam Structured-Light Scanning for 3-D Object Modeling
In this papel; we present our Dual-Beam StructuredLight Scanner (DSLS), a scanning system that generates range maps much richer than those obtained from a conventional structured-light scanning system. Range maps produced by DSLS require fewer registrations for 3 0 modeling. We show that the DSLS system more easily satisfies what are often dificult-to-satisfy conditions for determining the 3-0 ...
متن کاملBeam alignment for scanning beam interference lithography
By interfering two small diameter Gaussian laser beams, scanning beam interference lithography ~SBIL! is capable of patterning linear gratings and grids in resist while controlling their spatial phase distortions to the nanometer level. Our tool has a patterning area that is up to 300 mm in diameter. The motive for developing SBIL is to provide the semiconductor industry with a set of absolute ...
متن کاملBeam-scanning Multiphoton Multimodality Endoscopy
Two-photon-exciter fluorescence (2PEF) imaging and second-harmonic generation (SHG) microscopy has become well-established techniques for biomedical imaging [1]. Integration of fibers into the multiphoton microscopy system further enables in vivo and noninvasive investigation of biological samples. Nonetheless the broadening of ultrashort pulses in fibers has greatly hampered the development of...
متن کاملScanning Electron Beam Profile Monitor
A scanning beam profile monitor is described that was developed for use along the Stanford two-mile linear accelerator. The maximum beam loss due to scattering caused by this monitor can be made to be a small fraction of that which would be caused by a Cerenkov radiator or scintillating screen. (To be submitted to the Review of Scientific Instruments) * Work supported by the U. S. Atomic Energy...
متن کاملoving Beam Helical CT Scanning
Images generated with helical scanning are degraded by partial volume artifacts caused by an increased slice thickness when compared to conventional computed tomography (CT) scanning. The slice thickness for a helical scan is proportional to the sum of the thickness of the fan of radiation and the distance the patient moves during data acquisition. We present a method called moving beam helical...
