In this talk we will discuss
theoretical and computational studies of high
energy Lasers in turbulent atmospheres
incorporating thermal blooming. We will also
discuss certain novel ways to utilize a well
known transform in quantum physics to
convert the HEL propagation problem to that
of quantum fluid dynamics. This method
allows us to view the adaptive phase
compensation problem for electromagnetic
wave propagation as a control problem for
quantum fluid flow.
A second problem we will
discuss involves rapid detection of Laser attack
based on off-axis intensity measurements.
Here the challenge is to detect the power level
and other characteristics of enemy Lasers
based on ground-air-space based sensor
measurements off-axis to the propagation
path of the Laser.
Dr. Sritharan received a BSc in M.E. from U.of
Sri Lanka, MS from U. of Washington
(Seattle), and Ph.D. in Applied Mathematics
from the U. of Arizona (Tucson). He has been
a faculty member of U. Sri Lanka, U. Southern
California, and U. of Wyoming, and has held
visiting positions at several international
institutions. He is currently serving as Provost
and Vice Chancellor at the Air Force Institute
of Technology. Dr. Sritharan is widely
published in aeronautical sciences and in
defense relevant mathematical science. His
research focus has been on the subjects of
aerodynamics, electromagnetics, control
theory and stochastic processes, motivated
by defense science and technology
requirements such as enhancing autonomy
for unmanned aerial systems, directed
energy weapons, signal and signature
intelligence, etc.
