Printed Circuit Board Evaluation by Holographic Interferometry
Review of Scientific Instruments, 1972Application of real time holographic interferometry for the examination of a printed circuit board is described. The procedures and the resulting holographic interferograms of two specific studies are presented: (1) The heat conduction of a spacer used for mounting transistors on a heat sink, and (2) the detection of inner layer short circuits on a ...

Printing Of Holographic Stereogram Using Liquid-Crystal TV
SPIE Proceedings, 1989Multiplrex Holograms are printed by using a liquid-crystal television receiver as a spatial light modulator instead of silver-halide movie film. Reconstructed 3-D images of wire-frame model can be observed with high contrast. But, some noise which is caused by LCTV is also observed.

Dual-Polarization Printed Holographic Multibeam Metasurface Antenna
IEEE Antennas and Wireless Propagation Letters, 2017Multibeam antennas have emerged as a promising concept for applications where selective beam coverage is required. Multibeam radiation can be achieved leveraging the concept of metasurfaces, enabling the radiated wavefronts to be tailored in an all-electronic manner, making reconfigurable multibeam operation possible without the need for bulky feeding ...
