Sensing with electromagnetic radiation: a review. Part 1: Short wavelengths

Abstract

Purpose

The purpose of this paper is to provide a review of the industrial sensing applications of electromagnetic radiation (EMR) with an emphasis on wavelengths other than visible light. The paper is in two parts. This, the first, considers radiations with shorter wavelengths than visible light, i.e. γ radiation, X‐rays and ultra‐violet (UV).

Design/methodology/approach

The paper discusses the sensing applications of short wavelength EMR through reference to the techniques employed, products and their uses.

Findings

The paper shows that γ radiation, X‐rays and UV radiation are used in a wide range of industrial sensors for the measurement of physical variables, chemical compounds and gases. The phenomena employed include absorption, backscatter, photoionisation, fluorescence and reflection. Applications are extremely varied and embrace a diversity of industries.

Originality/value

The paper provides a detailed, technical review of the sensing uses of short wavelength EMR.
