What information does light, reflected from a running electronic device, carry? Our research team has been working upon this key question for almost a decade. As this magazine is dedicated to thermal issues, we will focus upon these aspects of optical probing. Figure 1 shows the general principle of our experimental method. Light is shone upon a running device. When the device … [Read more...]

Effects of electrical noise on thermocouple measurements
Measurements of temperature in electronic equipment and in thermal characterization apparatus are most often made with thermocouples. As with any sensor, the goal is to gather information about the environment in the vicinity of the sensor, in this case the temperature. Unfortunately the environment around the entire instrumentation chain, including the lead wires and the data … [Read more...]
