“…3), especially in the Fourier transform infrared (FTIR) machines used for absorption spectroscopy and the relatively new field of optical coherence tomography [21]. One example of a fiber optic based interferometric sensor is the commercially available intracranial fluid pressure monitoring system for patients with severe head trauma or a condition known as hydrocephalus, which is an increased amount of cerebral spinal fluid in the ventricles and/or subarachnoid spaces of the brain [22]. In addition, the Michelson interferometer is currently being investigated for sensing other biophysical parameters such as tissue thickness, particularly for corneal tissue as feedback for the radial keratectomy procedure, which is laser removal or shaving of the cornea to correct vision [23], [24].…”

Abstract-Recent progress in biomedical sensing technologies has resulted in the development of several novel sensor products and new applications. Modern biomedical sensors developed with advanced microfabrication and signal processing techniques are becoming inexpensive, accurate, and reliable. A broad range of sensing mechanisms has significantly increased the number of possible target measurands that can be detected. The miniaturization of classical "bulky" measurement techniques has led to the realization of complex analytical systems, including such sensors as the BioChemLab-on-a-Chip. This rapid progress in miniature devices and instrumentation development will significantly impact the practice of medical care as well as future advances in the biomedical industry. Currently, electrochemical, optical, and acoustic wave sensing technologies have emerged as some of the most promising biomedical sensor technologies. In this paper, important features of these technologies, along with new developments and some of the applications, are presented.

Fiber optic intensity-modulated sensors: a review in biomechanics

Fiber optic sensors have a set of properties that make them very attractive in biomechanics. However, they remain unknown to many who work in the field. Some possible causes are scarce information, few research groups using them in a routine basis, and even fewer companies offering turnkey and affordable solutions. Nevertheless, as optical fibers revolutionize the way of carrying data in telecommunications, a similar trend is detectable in the world of sensing. The present review aims to describe the most relevant contributions of fiber sensing in biomechanics since their introduction, from 1960s to the present, focusing on intensity-based configurations. An effort has been made to identify key researchers, research and development (R&D) groups and main applications.

“…Information on the density of these ions is useful when examining the behaviour of coronas, and for applications based on the charging effect of the ions, as in photocopiers and electrostatic precipitators. A possible optical fibre method of ion density measurement is one which uses a fibre Fabry-Perot interferometer with one reflecting surface in the form of an insulating membrane as one type of pressure-measuring device (Wolthuis et al 1991). Charge on the outer membrane surface induces charge on the second surface of the interferometer and the resultant electrostatic force alters the cavity length.…”

A consequence of the development of optical fibre technology for communications has been the application of optical fibres to the sensing of a wide range of physical and chemical parameters. Many of the properties of fibres that are important for communications' are significant for sensing: these include their insulating nature, their small dimensions, and their immunity to high voltage and electromagnetic radiation. These attributes are particularly significant for sensing electrical discharges, and this review presents a discussion of the potential of optical fibre sensing for discharge parameters, the results of some recent optical fibre measurements made on corona and glow discharges, and suggestions for other discharge. probing approaches using optical fibres.
