The measurement of image disparity is a fundamental precursor to binocular depth estimation. Recently, Jenkin and Jepson (1988) and Sanger (1988) described promising methods based on the output phase behaviour of band-pass Gabor lters. Here we discuss further justiication for such techniques based on the stability of band-pass phase behaviour as a function of typical distortions that exist betw...

Temperature measurement in microwave systems is essential for thermally driven processes, namely, catalytic reactions and ceramic sintering. Although, the application of direct thermometry methods, namely, thermocouples, have been commonly articulated in the available literature, however, contacted temperature measurement mechanisms have aroused concerns associated with the disruption of the el...

This paper introduces an interferometric technique for the phase measurement of microwave devices. A handheld vector network analyzer (VNA) is presented for HF and VHF applications. A wideband synthesizer with multiple synchronized outputs is developed for extending the frequency range to the microwave band. The phase differences between the output signals can be set digitally with sub-degree a...
