1. A portable, moveable or stationary mounted imaging system comprising:

  • a transmission source, said transmission source providing at least one energy pulse;

    a sensor for receiving pulse reflections of said at least one energy pulse reflected from objects within a depth of a field to be imaged, characterized in that said depth of field having a minimal range, RMIN, said sensor enabled to gate detection of said pulse reflections, with a gate timing controlled such that said sensor starts to receive said pulse reflections after a delay timing substantially given by the time it takes said at least one energy pulse to reach said minimal range and complete reflecting to said sensor from said minimal range, wherein each of said at least one energy pulse and said gate timing are controlled for creating a sensitivity as a function of range for said system, such that an amount of received energy of said pulse reflections, reflected from objects located beyond said minimal range, progressively increases with the range along said depth of a field to be imaged.
