20150160613 | RECONSTRUCTION OF AN IMAGE OF AN OBJECT AT LEAST PARTIALLY HIDDEN BY A FLAME - It is disclosed a system for reconstructing an image of an object hidden by a flame. The system comprises a laser source emitting an infrared radiation and a lensless, off-axis interferometric arrangement that divides the infrared radiation into an object beam and a reference beam. The object beam is enlarged and then irradiates the object, that scatters it. The reference beam is enlarged and then interferes with the scattered object beam, so as to create a hologram. The system comprises an infrared detector which detects the hologram and a processing unit which reconstructs the image of the object by numerically processing the hologram. The system therefore provides the object image based on digital holography at infrared wavelengths. Differently from known thermographic acquisition techniques, even if large portions of the object are hidden by the flame, the system allows to reconstruct an image of the whole object, with no blind areas. | 06-11-2015 |
