Far Infrared based Life Detection System to Rescue Alive Victims under Debris

A brief review of the conventional life detection systems is carried out and the design of a novel system using Far Infrared (FIR) region of the infrared spectrum is proposed. FIR rays with the wavelength range 1mm to 1μm are currently being explored by scientists for its biological effects. This paper puts forth the idea of using these rays in rescue operation systems subsequent to disasters like earthquakes to save the people trapped under the wreckage. Detection of life can be accomplished based on the changes in the properties exhibited by FIR rays when they are absorbed and radiated back by the living matter and reflected by the nonliving materials. By detecting the presence of life in the victims, a lot of time for rescue can be saved and mortality rate can be significantly reduced.
