Abstract:
A method and apparatus is provided for selectively attenuating narrowband high intensity bright sources from an incoming light source in an imaging system creating a focal plane array. The method comprises receiving and conditioning incoming light in a at least one group of optics; receiving the into a line attenuation tunable optical filter (LATOF) which creates a rejection band; tilting the LATOF at least one increment to selectively attenuate the bright sources from the receive conditioned light; receiving the conditioned light and selectively attenuated light into an opto-electronic detector; and converting the light into an output for an electronic image, wherein saturation of the focal plane array decreases and contrast is restored in the electronic image.
