A novel method for the determination of color matching functions

A novel method for the determination of color matching functions An instrument was developed for the psychophysical measurement of color matching functions. The instrumental design centers around the use of lasers as the primary light sources. The three (RGB) laser beams are independently controlled with acousto‐optic modulators and projected into a diffuser for color mixing. The instrument was designed to allow for free viewing of the matching fields and versatility in the implementation of the matching fields and surround. To simplify data collection, a model was developed that allows the computation of the full spectral tristimulus functions based on just five visual matches. This model expresses color matching functions as linear transforms of the cone action spectra multiplied by variable transmittances of the lens and macula. The model was tested using the 2° color matching data of Stiles and Burch, and preliminary data were collected and modeled using the new instrument. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Color Research & Application Wiley

Abstract

An instrument was developed for the psychophysical measurement of color matching functions. The instrumental design centers around the use of lasers as the primary light sources. The three (RGB) laser beams are independently controlled with acousto‐optic modulators and projected into a diffuser for color mixing. The instrument was designed to allow for free viewing of the matching fields and versatility in the implementation of the matching fields and surround. To simplify data collection, a model was developed that allows the computation of the full spectral tristimulus functions based on just five visual matches. This model expresses color matching functions as linear transforms of the cone action spectra multiplied by variable transmittances of the lens and macula. The model was tested using the 2° color matching data of Stiles and Burch, and preliminary data were collected and modeled using the new instrument.
