Abstract: Since its discovery in 1947 by Denis Gabor, Holography was shown to be a powerful tool to perform “real” 3D imaging and optical metrology. The development of high-resolution CCDs and powerful processors during the last decades opened new opportunities to apply digital holography in different domains. Digital holography combines the interferometric recording of the light scattered from the object and the back-propagation computation of the interference pattern to retrieve the 3D information of the object. Most of the recent developments and accomplishments in digital holography were based on a single-wavelength configuration. However, a multiple-wavelength is necessary to obtain the true color of the object or the absolute value of the measurement. This presentation will focus on my contribution in multiple-wavelength digital holography applied in several projects (aerodynamic flow visualization, mechanics, electronics, etc).
