Infrared Digital Holography Allows Firefighters to See Through Flames
Seeing through smoke and walls of flame to find people in need of rescue is one of a firefighter's greatest challenges. Researchers from Consiglio Nazionale delle Ricerche (CNR) Istituto Nazionale di Ottica in Italy have developed a new imaging technique that uses infrared (IR) digital holography to peer through flames and capture potentially lifesaving and otherwise hidden details. Other applications could include monitoring breathing, cardiac beat detection and analysis, and body deformation measurements during exercise. This video shows a comparison of a traditional imaging system, in which the view of a man is obstructed by flames, and the new technique, in which the viewer can see the man standing and waving his hand.
