|Sensitivity Issues in Step-Scan FT-IR Spectrometry
First we need to look at the differences in
performance between step-scan and conventional FT-IR, and then follow through to the
differences in operation. Then we will analyze the clues accumulated from many step-scan
measurements that point to the nature of the excess noise. This will lead to some likely
sources of instability in FT-IR spectrometers, and finally I'll show some results that
confirm that this is the right approach.
