A system and method for viewing objects at a fire scene allows fire fighters to view objects, including persons, in a smoke and fire filled environment. The present invention utilizes two different techniques to discriminate reflections from an object from scattered reflections from smoke and fire. In one embodiment of the invention, the coherent nature of laser light is employed to pick out objects. Another embodiment of the invention utilizes a time-gated approach to select reflections from objects which are located a specific distance from the laser transmitter.

A modulated LIDAR system is disclosed, in which a laser for generating an tical carrier signal and a microwave generator for generating a coded microwave signal are provided. A modulator is further provided for modulating the carrier signal with the microwave signal, whereby a modulated signal is generated. A method of detecting a reflective surface is also disclosed, in which an optical carrier signal is generated, the carrier signal is modulated with a coded microwave signal, the modulated signal is reflected off of a reflective surface and the reflected signal is recovered.

An actively pumped optical filter includes a vapor cell having a population of electrons with the plurality of energy levels which receives light and transmits light according to a pumping mechanism. A magnetic source is provided for applying a magnetic field to the vapor cell. A first pulsed dye laser applies a first beam of light to the vapor cell causing transitions of the electrons from a first energy level to a second energy level. A second pulsed dye laser is used for measuring the transmission through the vapor cell. A third laser applies a beam of light to the first laser and a beam of light to the second laser. The third laser may be an Nd:YAG laser. Polarizers are disposed before and after the vapor cell and a delay path is provided for delaying the second beam of light before the second beam of light is applied to the laser cell. The delay path is tuned by adjusting the length.
