This report describes a set of aerosol measurements to |
|
determine the effect of a countermeasure smoke, white |
|
phosphorus (WP), on a pulsed high-energy laser (HEL) |
|
beam. An analysis of the aerosol (gaseous and particulate |
|
airborne material) was used as the basis for calculations |
|
of evaporative clearing, and application was made to a |
|
given specific test situation. Linear propagation |
|
properties forming the basis for the 10.6 micrometers |
|
pulsed laser nonlinear effects are obtained relatively |
|
directly by using spectrophone absorption and extinction, |
|
a light scattering particle spectrometer and |
|
nephelometers (particle density as a function of radius |
|
and mass loading), and dew-point hygrometer (partial |
|
pressure of water vapor). General conclusions are that, |
|
for the smoke produced by burning WP, a CO2 pulsed HEL |
|
beam clears the optical path quite rapidly and |
|
efficiently. The absorption after clearing is caused by |
|
the residual vapors and is much lower. (Author) |
