ABSTRACT:
A two-color reading system includes binary encoders for signals of wide and narrow wavelength ranges. The reference level of the narrow wavelength encoder is set proportionately to the level of the wide wavelength signal by means of a voltage divider, so that the second color of the two color system may be more accurately separated.
