We present a series of experiments to demonstrate digital holography on reflective objects at wavelength 10.6 (mu)m of a CO_(2) laser using a pyrocam array. Fresnel holograms of reflective objects are recorded by a Mach-Zehnder 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.
