Because the technology uses a scanning beam to paint the image on the retina, Microvision calls a device using this technology a retinal scanning display -- not to be confused with the biometric technology of retinal scanning, which detects the distinctive pattern of blood vessels on the retina, a pattern that can be analyzed to identify someone, similar to the way fingerprints are used.
Using a scanning electron beam, line structures with both branched and unbranched morphologies were also obtained.
It is also worth mentioning that intensity modulation using a scanned pencil beam has also been applied to proton radiotherapy; dose distributions are superior to those achievable with the more commonly employed passively scattered proton beams (Weber et al, 2004), and there is also less total body neutron dose from beam-shaping devices (Miralbell et al, 2002).
Multiphoton and other nonlinear microscopies use a scanned laser beam for excitation since the optical response is nonlinear with the laser power density.
A CCD camera scintillation screen system, which can verify the 2D dose distribution of a scanning beam and can be used for proton radiography, was developed.
They used a scanning technique called electron-beam computed tomography to spot excess calcium buildup in the arteries--a marker for early-stage atherosclerosis.
Adhered particles were dissected using a dual-beam scanning electron microscope/focused ion beam (SEM/FIB) for morphological and microstructural examination.
The reflected beam was raster scanned using a two-axis beam-scanning unit (GSI Lumonics, Billerica, MA, USA) and focused onto the sample by a Nikon 60X 1.2 NA water-immersion objective (mounted above the sample using custom-built hardware).
Transmittance was compared using a double beam UV/VIS scanning spectrophotometer (Cecil-CE 7200-series, Aquarius, London, UK) at 456 nm wavelength and the amount of L-dopa produced was determined from the standard curve.
The third-order nonlinear optical properties of the target molecules have been investigated in N,N-dimethylformamide using a single beam Z-scan technique with nanosecond laser pulses at 532 nm.
