Digital Holographic Interferometry by Using Long Wave Infrared Radiation (CO2 Laser)

Abstract:

Article Preview

We show how digital holographic interferometry in the Long Wave InfraRed spectral range (LWIR) can be used for the investigation of mechanical structures. The 10.6 μm radiation is produced by a CO2 Laser. Experimental results showing that the method can be used to locate defects in a panel are presented and advantages and disadvantages of this approach are discussed.
