Method for making an array of micro-needles

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 processor that reconstructs the image of the object by numerically processing the hologram.

Reconstruction of an image of an object at least partially hidden by a flame

A holographic method with numerical reconstruction for obtaining an image of a three-dimensional object, employs a digitalized hologram of an object or of a portion thereof, and includes starting from the digitalized hologram, extracting a phase image of the object corresponding to a matrix MD of distance values, selecting a subassembly SD of the distance value assembly present in matrix MD, subassembly SD containing distance values d, extracting from matrix MD an iso-level assembly IQdof corresponding bidimensional coordinate of the object; reconstructing, for each distance value d, a bidimensional matrix IMdof intensity values relevant to the object; extracting, from each bidimensional matrix IMd, a bidimensional IFdof intensity values; and starting from the intensity values, reconstructing the three-dimensional intensity image of the object.
