Title (EN) A METHOD AND APPARATUS FOR MEASURING THE FREQUENCY OF RADIATION
(FR) PROCEDE ET DISPOSITIF DE MESURE DE LA FREQUENCE D'UNE RADIATION
Abstract: front page image
(EN)Method and apparatus for measuring the frequency of radiation comprising a pair of filters (2, 3) or a beam splitter (30) responsive to radiation from a source of radiation (4) for providing a first output having a magnitude which increases and a second output having a magnitude which decreases with an increase in the frequency of said radiation, a divider (11) for providing a ratio of the magnitudes of said first and second outputs and a comparator (14) and memory (17) responsive to the ratio from said divider (11) for providing an output corresponding to the frequency of said radiation.
(FR)Procede et dispositif de mesure de la frequence d'une radiation comprenant une paire de filtre (2, 3) ou un diviseur de rayons (30) sensible a la radiation d'une source de radiation (4) fournissant une premiere sortie possedant une grandeur croissante et une deuxieme sortie possedant une grandeur decroissante lors de l'augmentation de la frequence de ladite radiation, un diviseur (11) fournissant un rapport entre les intensites desdites premiere et deuxieme sorties et un comparateur (14) et une memoire (17) sensible au rapport fourni par ledit diviseur (11) de facon a fournir une sortie correspondant a la frequence de ladite radiation.
