title: [Determination in the spectral curve of relative luminous efficiency (author's transl)].
abstract: The determination of the maximum in the spectral curve of relative luminous efficiency can be done with a simple procedure. Two colours having the same ordinate on the curve are alternatively presented at a rate under the critical fusion frequency. They do not flicker if the subject is normal. They flicker on the contray if the maximum is displaced. We developed a simple apparatus which is proposed.
