ABSTRACT This Letter presents a method for real-time 3D measurements based on three-color digital holographic interferometry. The optical setup is considerably simplified, since the reference beams are combined into a unique beam. A convolution algorithm allows the three monochrome images to be superposed to provide simultaneous full-field 3D measurements. Experimental results confirm the suitability of the proposed method.

    • "However, such an architecture guarantees a maximum spatial resolution since the number of effective pixels for each wavelength corresponds to that of the full sensor. Recently, authors have first evidenced that digital color holograms could be recorded/reconstructed, thanks to a sensor based on a strategy using a stack of photodiodes with 1060 Â 1414 pixels sized 5 Â 5 mm 2 [15] [16] [17] [18] "

    ABSTRACT: This paper presents the experimental optical analysis of the crack inside an electronic component. The optical setup is used to carry out multidimensional deformation measurements using digital color holography and the spatial multiplexing of holograms. Since the Fresnel transform method depends on wavelength, a wavelength-dependent-zero-padding algorithm is described and results in a rigorous sizing of each reconstructed monochrome image. The criterion to optimize the parameters is presented and is based on minimizing the widening of the impulse response of the full recording/reconstruction process. The application of the proposed method is illustrated through the analysis of the mechanical deformation of the electronic component, and offers keys to understand its failure mode in industrial conditions.

    • "The movie shows convective flows induced by thermal dissipation in a tank filled with oil [9]. Recently, we have to also mention Picart'works where the three-sensitivity measurements have been obtained in real-time from three threewavelengths and three sights of view for the reference waves [10].

    ABSTRACT: This letter presents a method for real-time three-color digital holographic interferometry based on Foveon CCD. The control mode of CCD is optimized and color aliasing is limited consumedly. The influence on color hologram becomes very little. On the whole, color aliasing is eliminated especially in the phase difference detecting. Moreover, the optical setup is considerably simplified, since the reference beams are combined into a unique beam. Experimental results confirm the suitability of the proposed method.
