发明名称 Filter Design for Colorimetric Measurement
摘要 A color detector includes a light source configured to generate light with a spectrum of wavelengths; a plurality of filters in optical communication with the light source, wherein each filter is configured to pass a bandwidth of wavelengths around a different peak wavelength; and a plurality of photodetectors, each configured to receive light passed through a respective filter of the plurality of filters. The bandwidth of each filter is configured to Correspond to a bandwidth of a curve from a set of standard color matching functions. A method for improving color detection accuracy in a color detector includes matching a bandwidth passed by each of a plurality of color filters with a bandwidth and peak wavelength of a Commission Internationale de I'Eclairage (CIE) color matching function; and separately detecting an amount of light passed by each the filter.
