Abstract

L'invention se rapporte à un circuit de balayage suivant des courbes de la famille de Lissajous. Il comprend un unique générateur de signal électrique, dont la fréquence est fonction de la température. Ce signal est appliqué à au moins deux diviseurs de fréquences, au moins deux filtres, au moins deux déphaseurs. Le circuit selon l'invention, permet de balayer simultanément une caméra, par exemple du genre microendoscope à lames vibrantes, et un système de visualisation. Application : caméra micro-endoscopique.
