1. A system for three-dimensional imaging of an object comprising:

  • an imaging sensor comprising a focal plane array and a sensor controller; and

    a laser illuminator coupled to said sensor controller;

    wherein said laser illuminator is adapted to emitat least one laser pulse to be reflected from at least one plane of said object and detected by said focal plane array as at least one two-dimensional image frame of light intensities so as to provide range information and relative contrast information of said plane of said object, wherein said sensor controller isadapted to associate a range dimension of said plane with said two-dimensional image frame to facilitate formation of a three-dimensional image of said object, and wherein said sensor controller is adapted to activate and deactivate said sensor, to generate from a single laser pulse a single two-dimensional image frame for a single time period wherein each said two-dimensional image frame includes an array of three dimensional volume pixels associatedwith said plane of said object, wherein successive single laser pulses generate successive two-dimensional image frames, and wherein said two-dimensional image frames collectively provide a three dimensional array of said volume pixels to provide a three dimensional image of the object.
