Using non-linear optics to shine light on aerospace engineering challenges

Using non-linear optics to shine light on aerospace engineering challenges

Sir Horace Lamb famously said that “I am an old man now, and when I die and go to heaven, there are two matters on which I hope for enlightenment. One is quantum electrodynamics and the other is the turbulent motion of fluids. About the former, I am really rather optimistic.” Although nowadays we can travel in less than a day’s time from Perth, Australia to London, UK, and from Newark, USA to Singapore, there are still many open scientific questions in the aerospace engineering realm, especially when it comes to supersonic and hypersonic flight. Mastering hypersonic wind tunnels is one key component of the research involved but advanced, accurate and non-perturbative diagnostics is another key part. In this talk I will discuss laser diagnostic efforts developed to tackle the latter, by concentrating on the research efforts of our group in this field by utilizing Coherent Rayleigh-Brillouin scattering (CRBS).
