如何由色坐標(biāo)求它的波長，有什么公式嗎？謝謝！

有哪位高手知道的嗎???急急急

Hi, !}[}YY?',i

Here is a method besed on CIE1931 system: 
X'Q?Mh  
I!eu|_cF  
1) Try to find the intersection point of  CIE1931 standrad curve and the following line: 6?$yBu9l  
  y=k*(x-0.3333) + 0.3333  DA]<30w  
   here
Ne#FBRu5  
   k=(yo-0.3333)/(xo-0.3333) and (xo,yo) is the known color coordintae point. 1yC_/Va1  
;-sZaU;  
2) the wavelength of the intersection point will be the dominant wave to be determined. Heh.CD)Q  
=z^2KH  
If you need further help, I can share an Excel file. -<H\VT%98

Let me know how thing's going. `yF6-F

如果你說的波長是主波長(dominant wavelength)，那么上面方法合適你用
