Abstract:
An apparatus comprising:a vehicle with an actuatable system; a first photosensor with a first peak spectral sensitivity to a first wavelength, said first photosensor receiving light and producing a first electrical signal in response thereto; a second photosensor with a second peak spectral sensitivity to a second wavelength, said second photosensor receiving light and producing a second electrical signal in response thereto; and a controller for receiving the first electrical signal and the second electrical signal, said controller actuating said actuatable system in response to the first electrical signal and the second electrical signal; wherein the second wavelength is at least about 150 nanometers less than the first wavelength, the first wavelength is greater than about 750 nanometers, and the second wavelength is less than about 750 nanometers.
