Abstract
Apparatus for detecting airfield light emitters, the apparatus including a plurality of light detection cameras, each detecting at least one respective waveband of electromagnetic radiation within the electromagnetic spectrum, each of the light detection cameras producing a plurality of respective spectral images, and a processor coupled with the light detection cameras, thereby generating a multispectral image of the airfield light emitters from the spectral images, the multispectral image including a multi-dimensional set of spectral values, wherein the processor further determines which combination the multi-dimensional set of spectral values corresponds with a plurality of distinct light emission characteristics of the airfield light emitters by identifying a particular spectral signature corresponding to the multi-dimensional set of spectral values, wherein the processor produces an enhanced image from those spectral values of the multi-dimensional set of spectral values which correspond to the determined combination.
