Metrology II

by Dr. Heinz Reichert

 

Part 1: Measuring the temperature-time history of a free-falling sample in a vacuum drop tube

This section explains how ratio pyrometry works at two or three wavelengths and illustrates how a guided sensor alignment can be used to reliably achieve a signal‑to‑noise ratio greater than one.
