Abstract

PROCEDE ET APPAREIL UTILISANT UN RESONATEUR A CRISTAL DE QUARTZ D'UNE ORIENTATION SENSIBLEMENT EGALE A (YXWL) 21.9333.93 VIBRANT SIMULTANEMENT SUR DEUX MODES SUIVANT L'EPAISSEUR. EN COMBINANT UN RESONATEUR A CRISTAL DE QUARTZ DU TYPE CI-DESSUS AVEC UNE COMPENSATION NUMERIQUE OU ANALOGIQUE, ON PEUT UTILISER LA DEVIATION EN FONCTION DE LA TEMPERATURE DE L'UNE DES FREQUENCES DES MODES DU CRISTAL COMME THERMOMETRE INTERNE ET LA FREQUENCE DU SECOND MODE DU CRISTAL COMME SIGNAL A FREQUENCE DE REFERENCE. LE SIGNAL DE FREQUENCE ASSURANT LA FONCTION DE THERMOMETRE EST UTILISE PAR LE RESEAU DE COMPENSATION POUR CORRIGER LES MESURES EFFECTUEES AVEC LA FREQUENCE DU SIGNAL A FREQUENCE DE REFERENCE OU POUR STABILISER CETTE FREQUENCE. APPLICATION NOTAMMENT COMME SOURCE DE FREQUENCE STABLE OU POUR MESURER EN MEME TEMPS FREQUENCE-TEMPERATURE.
