Comparison of 294 nm and 355 nm excitation wavelengths in UVLIF standoff detection of biological aerosols released in a semi-closed chamber
Farsund, Øystein; Rustad, Gunnar; Skogan, Gunnar (2012-02-07)FFI has previously developed a lidar for standoff detection of biological aerosols based on ultraviolet laser induced fluorescence, using an excitation wavelength at 355 nm. A 294 nm laser source has been developed and ... -
Design of a high pulse energy coherent ultraviolet source - simulations and experimental design
Rustad, Gunnar; Farsund, Øystein (2013-02-01)The report discusses design considerations and numerical simulations of different system architectures for generation of several tens of mJ pulse energy in the ultraviolet range around 290- 300 nm. The architectures ... -
Sensor installation on KNM Skjold prior to firing tests April 2000
Farsund, Øystein; Sagvolden, Geir; Pran, Karianne; Wang, Gunnar (2000)This document describes the installation of resistive strain gauges, Bragg grating strain sensors, pressure sensors and accelerometers prior the cannon firing tests carried out on KNM Skjold in April 2000. Figures of the ... -
Standoff detection of biological aerosols by means of UV-laser induced fluorescence : results from Umeå trial 2006
Farsund, Øystein; Rustad, Gunnar (2008)The objective of standoff detection is to enable early warning in case of a biological warfare agent attack. FFI has built a demonstrator employing ultraviolet laser induced fluorescence of biological aerosols. The field ... -
Standoff detection of biological aerosols by UV-laser induced fluorescence
Rustad, Gunnar; Farsund, Øystein (2008)Denne rapporten beskriver et eksperimentelt instrument som kalles biolidar og som er utviklet ved FFI i perioden 2005-2007. Biolidaren har som formål å oppdage aerosoler med biologisk innhold for å kunne gi tidlig oppdagelse ... -
Strain measurements : a comparison of strain gauge and fiber bragg grating measurements on KNM Skjold
Farsund, Øystein; Pran, Karianne; Wang, Gunnar; Sagvolden, Geir (1999)Strain measurements by means of resistive strain gauges and fiber optic Bragg gratings during the sea-keeping tests of KNM Skjold have been analyzed and compared. The resistive strain gauge measurements were severely ...
