| Sumario: | This contribution corresponds to a laboratory work for a course in Holography and Optical Image Processing in a master degree. The spatial light modulators allow the display of computer generated holograms in real time. They permit the study of the features of image formation by holograms. We use a spatial light modulator made with a liquid crystal panel and polarization devices to get either amplitude or phase only responses. A convergent difractometer has been built to obtain the impulse response of the Fourier holograms. Different strategies to design the holograms have been proposed and experimental results are given. © 2005 SPIE. |
