Creating an equivalent field source is an efficient method for predicting radiated emissions from IC structures. In this paper, the maximum radiated emissions for a heat-sink/IC structure is predicted by creating an equivalent source from the measured electrical field (E-field) in the gap between the heatsink and IC. The E-field is detected by an E-field probe made of an open coaxial cable coated...
The transfer impedance of a current probe is typically not constant within the current probe's operational frequency range. As it is based on induction, it will suffer from reduced sensitivity at lower frequencies. Thus, a current probe cannot be used directly in a time domain measurement. The low frequency roll-off of a current probe can severely distort the actual waveform. A simple frequency response...
Along with the continuous development of infrared guided missile and infrared imaging simulator, new requirements are put forward for the measurement range and calibration accuracy of infrared radiation measuring instrument. A new type of radiometric calibration system is development and used to realize radiation measurement of infrared imaging simulator, the calibration parameters consist of equivalent...
The Perspective-3-Point problem (P3P) is a classical and fundamental problem in computer vision. All possible solution sets for the P3P problem are from 1 to 4 solutions. In this paper, we propose a very simple way to reduce the ambiguity of numbers of possible solutions in P3P using a planar mirror. For three reference points, if they and their reflections in a planar mirror are both observed, we...
