Abstract
A system is configured to determine a color distribution of an object moving along a flow direction relative to a spatial filter. The light emanating from the object is time modulated according to the mask features of the spatial filter. First and second detectors are arranged to sense the modulated light. The first detector senses light having a first wavelength spectrum and generates a first electrical output signal in response to the sensed light. The second detector light senses light having a second wavelength spectrum and generates a second electrical output signal in response to the sensed light. Signals from the first and second detectors include information about color distribution of the object.
