We present a series of experiments to demonstrate digital holography on reflective objects at wavelength 10.6 lm of a CO2 laser using a pyrocam array. Fresnel holograms of reflective objects are recorded by a MachZehnder interferometer. We describe a method for improving the accuracy of the numerical reconstructions and for compensating the loss of resolution at longer wavelength by Fresnel reconstruction of digitally recorded infrared holograms.

Abstract
We present a series of experiments to demonstrate digital holography on reflective objects at wavelength 10.6 lm of a CO2 laser using a pyrocam array. Fresnel holograms of reflective objects are recorded by a MachZehnder interferometer. We describe a method for improving the accuracy of the numerical reconstructions and for compensating the loss of resolution at longer wavelength by Fresnel reconstruction of digitally recorded infrared holograms.File in questo prodotto:
