System for detecting an object at least partially hidden by a flame

A system for detecting an object at least partially hidden by a flame, the system comprising:

• a first portable device comprising a fiber optic laser suitable for emitting an infrared radiation;
• a second portable device comprising a fiber optic splitter optically coupled to the fiber optic laser and an infrared detector, the fiber optic splitter being configured to divide the infrared radiation into an object beam and a reference beam, to direct the object beam onto at least a portion of the object and to direct the reference beam onto the infrared detector, the infrared detector being configured to detect a hologram formed by the reference beam interfering with the object beam scattered by the at least a portion of the object,
• wherein the system further comprises a data processing unit configured to reconstruct at least one image of the object by numerically processing the hologram and a display configured to visualize the at least one reconstructed image.
