An improved three-dimensional imaging system for imaging an object including a plurality of resolvable elements includes: an amplitude modulated radiation source for transmitting radiation to the object (28); at least one photoelectric image detector (12, 14, 16); means for synchronously enabling the at least one detector during at least three portions of the period (37, 38, 39) of the modulated radiation source for detecting the radiation reflected from the object (36); means for calculating the phase angle between the transmitted radiation and the reflected radiation (40); and means, responsive to the means for calculating the phase angle for calculating the range of a plurality of elements of the object with respect to each other (40).

L'invention a pour objet un système amélioré d'imagerie tridimensionnelle, pour imager un objet comprenant plusieurs éléments séparables. Ce système se compose d'une source de rayonnements modulés en amplitude pour transmettre le rayonnement vers l'objet (28); au moins un détecteur d'image photoélectrique (12, 14, 16); des moyens pour valider de manière synchrone au moins un détecteur pendant au moins trois parties de la période (37, 38, 39) de la source de rayonnement modulé pour détecter le rayonnement réfléchi par l'objet (36); des moyens pour calculer l'angle de phase entre le rayonnement émis et le rayonnement réfléchi (40); et des moyens agissant en réponse au moyen de calcul de l'angle de phase pour calculer la pluralité des éléments de l'objet l'un par rapport à l'autre (40).
