French term or phrase:plan de rang
In a patent relating to a device for determining the intensity and phase of a light beam: "Le disposititif comprend des moyens pour mesurer l'intensité Ii du faisceau dans N plans. Les moyens de mesure de l'intensité comprennent un plan unique de capteurs et de moyens pour rassembler N faisceaux élémentaires distincts issues du faisceau de lumière cohérente sur N zones distinctes du plan unique de capteurs... Ce procédé comprend: le choix, pour le plan de rang i=1, d'une matrice de phase de départ et le calcul d'une matrice d'amplitude complexe, par produit term à terme de la matrice de phase avec la matrice d'amplitude correspondante;..."
Explanation: Or however you can best fit in "plane i".
If I understand correctly, there is a single array of sensors (arranged in a plane, presumably) which is used to measure light intensity at several places (planes/cross sections) in a beam, either by displacing the array along the beam or by refocussing the beam, or displacing the source, or something. Each location at which a measurement is taken will be "plane i", or plane No. 1, plane No. 2, etc.

Explanation: I'm pretty sure we're talking here about 'planes', and the only way I can interpret this would be 'plane where light level i = 1' --- it's one in a series of planes that are presumably being defined by the light level --- a bit like contours on a map or isobars, I guess?
Maybe 'level 1 plane' ?

rang d'une matrice n. m.
rank of a matrix
However Rank=1 is not a plain.it ust be at least 2, higher rank would be hyperplanes ... if it is an iterative algorithm for matrice calucalitons perhaps plane is used loosly
I could not be very sure.
