14. Full Color 3-D Imaging by Digital Holography and Removal of Chromatic Aberrations.

Author

Ferraro, P., Grilli, S., Miccio, L., Alfieri, D., De Nicola, S., Finizio, A., and Javidi, B.

Abstract

In color digital holography the recording and reconstruction of three holograms, by an optical setup operating in multi-wavelength mode, is necessary. Incorrect superposition of different images at various wavelengths may occur due to the presence of chromatic aberrations. We demonstrate that the compensation of the chromatic aberrations can be achieved by using all of the information contained in the multi-wavelength digital holograms. Chromatic aberration is extracted from phase maps reconstructed at different wavelengths, resulting in perfect full color amplitude reconstructions. The method has important applications in color 3-D holographic imaging and display. [ABSTRACT FROM PUBLISHER]

15. Controlling images parameters in the reconstruction process of digital holograms.

Author

Ferraro, P., Coppola, G., Alfieri, D., De Nicola, S., Finizio, A., and Pierattini, G.

Abstract

Digital holograms recorded with a charge-coupled device array are numerically reconstructed in amplitude and phase through calculation of the Fresnel-Kirchhoff integral. The flexibility offered by the reconstruction process in digital holography allows exploitation of new possibilities of application in microscopy. Through the reconstruction process we will show that it is possible to control image parameters as focus distance, image size, and image resolution. Those explored potentialities open further the novel prospective of application of digital holography in single- and multiwavelengths operation either for display or metrological applications. We demonstrate the concept of controlling parameters in image reconstruction of digital holograms in some real situations for inspecting silicon microelectronic-mechanical systems structures.

Abstract

A novel, simple and effective micromechanical technique for the synthesis of graphene supported by low density polyethylene (LDPE) is reported. This technique is based on the application of a combination of shear stress and friction force to nanographite to induce its complete exfoliation to graphene. LDPE-supported graphene multilayers of large area were prepared and their morphological, structural and electrical properties were investigated. The samples showed negative photoconductivity under white-light illumination, varying the power density from 27 to 170 mW/cm2.
