ABSTRACT:
An improved three-dimensional imaging system for imaging an object having a number of resolvable elements including: an amplitude modulated radiation source for transmitting radiation to the object; at least one photoelectric image detector; a gating circuit for synchronously enabling at least one of the detectors during at least three portions of the period of the modulated radiation source for detecting radiation reflected from the object; and a 3-dimensional image computer having a first routine for calculating the phase angle between the transmitted radiation and the reflected radiation and a second routine, responsive to the calculated phase angle, for calculating the range of the number of elements of the object with respect to each other.
