There was a BBC story about the devices, and they do exist, doing coarse frequency spectroscopy and time series analysis. Even if the scrotes don't believe they exist, are they willing to take the chance?
Having tried to post the links, there's now a question whether the automatic a-to-at-symbol conversion machine will let these links work.
Thanks for sharing these links, I appreciate it.
It seems to me that the forensic analysis of these airborne systems probably is a little coarser than implied by the analogy of matching a bullet to a gun in the BBC quote by chopper pilot Mike Briggs.
I was skeptical that the spectral measurement alone could distinguish a particular consumer grade laser unit. The Optra/NAVAIR paper in the links gives the actual measured wavelength resolution of the Laser Event Recorder as 7 nm.
But, the GPS data, the superimposed image of the offending site and the power measurement probably seal the deal for the judge when an arrest is made.
