Etalonnage absolu d’un spectrometre SISAM
Applied Optics, 1970A SISAM spectrometer was adjusted. It was fitted with an apparatus for measuring absolute wavelengths. This used the fringes of a Fabry-Perot with emission lines. The results indicate that the width of the apparatus function is less than 0.025 cm(-1) and that the relative accuracy of the wavelength measurements is 0.003 cm(-1).

Etalonnage de l’analyse spectrale par la méthode du modèle autorégressif
Annales des Télécommunications, 1981Dans l’etude de la densite spectrale de puissance d’un bruit blanc additionne a un signal a frequence pure par la methode du modele autoregressif, les auteurs etablissent une formule generale permettant d’etalonner cette methode d’analyse en fonction de l’ordre du filtre autoregressif et du rapport signal sur bruit d’entree.

Etalonnage de cales étalons angulaires par la méthode de zéro
Canadian Journal of Physics, 1981A method used to calibrate a set of reference angle gage blocks is described. Only the equipment usually found in a dimensional metrology laboratory is used, such as autocollimators and a surface plate. Contrary to some other well-known methods, supplementary sets of angle gage blocks, a high precision dividing head or a rotary table are not needed ...

Etalonnage des sondes parietales a film chaud en regime permanent
International Communications in Heat and Mass Transfer, 1985Abstract The utilization of hot film probes for the measurement of wall shear stress requires the realization of a calibration channel which permits to study the probes responses, to draw the calibration curves in laminar and turbulent flows and to propose the laws in the following form: Nu = K τ p ∗ n .
