The effect of turbulence on propagating laser
beams has been a subject of interest since the evolution of
lasers back in 1959. In this work, an inexpensive and reliable
technique for producing interferograms using a point
diffraction interferometer (PDI) was considered to experimentally
study the turbulence effects on a laser beam
propagating through air. The formed interferograms from
a propagating beamwere observed and digitally processed
to study the strength of atmospheric turbulence. This technique
was found to be sensitive enough to detect changes
in applied temperature with distance between the simulated
turbulence and laser path. These preliminary findings
indicated that we can use a PDI method to detect
and localise atmospheric turbulence parameters. Such parameters
are very important for use in the military (defence
laser weapons) and this is vital for South Africa (SA)
since it has natural resources, is involved in peace keeping
and mediation for other countries, and hence must have
a strong defence system that will be able to locate, detect
and destroy incoming missiles and other threatening atmospheric
systems in order to protect its environment and
avoid the initiation of countermeasures on its land.
