Paper Abstract

We propose a surveillance photonic fence for night remote intrusion detection, especially in bad environmental conditions. The photonic fence is established by the synchronization of a pulsed infrared laser and a gated imaging sensor. Since the wavelength of the laser is invisible, the photonic fence is also invisible. Only when targets pass the fence, their image information can be collected. Objects and backgrounds out of the fence are all filtered directly which decreases the complexity of image processing about target extraction. For the fence, its location can be easily adjusted by the delay time between the laser pulse and the gate pulse, and its thickness can be set by changing the gate time and the laser pulse width. Furthermore, target space information can also be estimated in terms of the range information of the photonic fence.
