3.3 - A miniaturized MID-IR-Spectrometer based on a linear variable filter and pyroelectric line array – Monitoring oil condition

Abstract

Miniaturized mid-IR spectrometers have an enormous potential to solve a plurality of different measurement problems. IR-Spectroscopy can be used for qualitative and quantitative measurements of chemical compounds and their concentrations in solid, gaseous and fluid phase. Building the IRspectrometer small, cost effective and robust without any moving parts enables an online or even inline measurement in process monitoring, health monitoring or quality control tasks.
