It uses pulsed light - emitting diodes (LEDs) with multiple
infrared (IR)
wave lengths, and combines specially - designed full red, green, blue (RGB) cameras to deliver stable detection.
«The nulling mode of the interferometer uses starlight across a wide range of wavelengths, including visible light for the adaptive optics to correct the telescope
wave - fronts, near -
infrared light to stabilize the path -
lengths, and mid-
infrared light for the nulling science measurements.»
One major simplification involves treating all the
infrared radiation (IR) as if it consisted of one
wave length, although the real situation is of course much more complicated with a
wave spectrum, selective absorption bands, and radiation with different frequencies and optical depths (Pierrehumbert 2011).
