The wavelength of the laser is 488 nm, and laser scanning is managed by a light polarization method using two galvano-meter scanner mirrors.
You first mount the sensor around your electric meter and position the optical scanner correctly which can be difficult, especially with older meters.
PMTs have to be replaced altogether or, as was the case in the first MR-compatible PET detector designs, positioned several meters away from the MR scanner, where the magnetic field strength is low enough.
The paper tracings were measured with the LI-3000 learearea meter, scanned with two flatbed scanners (CanoScan LiDE 20, Canon; MFC-J425w, Brother International) at 300 pixels per inch for ImageJ analysis, and photographed with 4-cm red calibration area using a camera phone (iPhone 4, Apple) for analysis with Easy Leaf Area.
A range of surveying equipment is available, with this chapter focussing on the common surveying systems encountered by researchers and students, namely engineer's/auto level, electronic distance meter, total station, and terrestrial laser scanner.
From the ground to the top of the scanner head is 7.5 meters.
The team closely examined the pajamas over a two week period, using electromagnetic field meters, non-contact thermal scanners, temperature probes, motion-sensitive still cameras, night-vision equipment, and wireless video surveillance.
The simulation ran at resolution of 0.85 meter, which is given by the resolution of the scanner multiplied by the model scale.
A meter long linear axis was used to automatically translate the scanner system horizontally.
In May US Airways supplemented the use of ID tags at the airport in Charlotte, North Carolina, and installed iris scanners that can, from a third of a meter away and in a fraction of a second, confirm a pilot's identity.
