Plastic optical fibres (POF) made of polymethyl methacrylate (PMMA) have several advantages over traditional optical fibres, including lower cost, the possibility of larger diameters and better mechanical resistance. These properties make them an attractive option for sensor technologies, including radiation dosimetry. This paper compares PMMA optical fibre with pure silica core optical fibre. Both fibres are useful for ionising radiation measurements. To evaluate the effect of ionising radiation, we have developed and designed a measurement system that allows continuous measurement of attenuation during the ionising radiation irradiation process. We used a technique that measured changes in laser power transmitted through an optical fibre at a constant gamma radiation dose rate.

“…Regarding aerospace engineering instrumentation, Ge et al [ 87 ] investigated the properties of several POFs (polystyrene—PS, polycarbonate—PC and PMMA) and their performance under exposure to high doses of gamma radiation. The authors concluded that the damage is dependent of the induced radiation wavelength.…”

The recent advances of polymer technology allowed the introduction of plastic optical fiber in sensor design. The advantages of optical metrology with plastic optical fiber have attracted the attention of the scientific community, as they allow the development of low-cost or cost competitive systems compared with conventional technologies. In this paper, the current state of the art of plastic optical fiber technology will be reviewed, namely its main characteristics and sensing advantages. Several measurement techniques will be described, with a strong focus on interrogation approaches based on intensity variation in transmission and reflection. The potential applications involving structural health monitoring, medicine, environment and the biological and chemical area are also presented.
