On the Basic Sensation Curves of the Three-Color Theory

摘要: A new method is described for the measurement of basic sensation curves three-color theory Young-Helmholtz.In order to determine spectral distribution absorption blue receptors a weak spot P that mainly excites projected on field F; this illuminated by monochromatic light with wave-length λ. Its energy per cm2E increased up E(λ) where becomes invisible. The leading idea sensitivity G(λ) inversely proportional E(λ). This means visibility better when excitation F small. Some restrictions are given in Section 2. In discussion an essential assumption difference cones or rods never observable if smaller than 1 percent. Evidence law given. When necessary, discrimination green red excluded adding appropriate amount illumination F. curve and may be found used. 3 apparatus described. 4 results measurements author’s left eye (deuteranomalous), normal trichromat, dichromat. deuteranomalous lies between curve. 5 some conclusions drawn from measurements. It shown so-called international z, which has its maximum blue, represents receptors; x y, however, must transformed. tentative transformation Finally it remarked our complete variance four-color theory.
