This thesis endeavours to record the development and subsequent evaluation of a simple technique for the recording of microwave holograms using common hardware components, which offers the possibility of significant improvements in image resolution. Practical experiment has determined that, under ideal conditions, the resolution performance of this system approaches very closely the theoretical maximum. Design aspects of the Q-band microwave source/receiver have been presented, and some emphasis placed upon the influence of antenna behaviour on hologram fidelity. Images reconstructed at optical frequencies from reduced size hologram transparencies have shown that accurate images are not possible in certain object formats -specular object reflections and the appearance of spurious images being two examples investigated. The possibility of imaging objects concealed by dielectric media has been demonstrated, and certain effects caused by the "phase-only" nature of the hologram can be explained. 2015-02-17T12:53:55Z 2015-02-17T12:53:55Z 1976 Master Thesis Masters MSc http://hdl.handle.net/11427/12491 eng application/pdf Department of Electrical Engineering Faculty of Engineering and the Built Environment University of Cape Town |
