Tests of the laser to relocate points in the field to within 0.20 m and 0.1°, averaged 0.42 m (S.D. 0.29) from the original points.
"When you're approaching that narrow of a line from a perpendicular angle, it tends to disappear," said Jim Patterson, an airport safety specialist for the federal aviation agency who is overseeing the research and testing of the Greatland Laser product.
This is necessary to perform test fires of the laser in order to ensure adequate wetting, i.e., polymer to tissue/slide contact.
The tensile shear test load of the laser-arc-adhesive hybrid welding of Mg to Al joints is 2.15 kN and 118 MPa without curing the adhesive.
In the present work, we have designed, developed, and tested a state-of-the-art laser-induced breakdown spectroscopy (LIBS) based optical sensor to detect four important trace level impurities (i.e. nitrogen, argon, oxygen, and helium) in hydrogen as a rocket fuel.
The first test of the airborne laser is scheduled in 2003.
A set of fixed samples were employed for testing the imaging capabilities of the laser system.
INFN-LNF SCF_Lab (Satellite/lunar/GNSS laser ranging/altimetry and Cube/microsat Characterization Facilities Laboratory) has been performing tests on a sample of the laser array segment under the Thermo-optical vacuum testing of Galileo IOV laser retro-reflectors of Galileo IOV LRA project, as defined in ESA-INFN Contract No. 4000108617/13/NL/PA.
ENEA has been deeply involved in the design, development and testing of a laser based In Vessel Viewing System (IVVS) required for the inspection of ITER plasma-facing components.
The mechanical high-cycle fatigue (HCF) testing of some laser preexposed specimens has also been conducted at 100 Hz to determine the laser surface damage effect.
