The magnetic resonance imaging (MRI) technique is a powerful diagnostic tool which is nowadays commonly used in many fields of medicine. In some cases, especially of the patients of intensive care units, it is highly recommended or even necessary to provide continuous monitoring of basic physiologic parameters, mainly the heart rate and the respiratory rate, during the MRI scan procedure. The presence of a strong magnetic field within the MRI chamber requires application of non-standard devices and solutions. The monitoring system needs to be immune to the strong magnetic field and simultaneously cannot negatively influence on the results of the scan. Therefore, application of optical sensing technologies could be potentially advantageous to fulfil these requirements. In this work we propose a novel optoelectronic measurement system, dedicated to monitoring of the patient during an MRI scan, immune to strong magnetic field and compatible with the MRI apparatus. Fiber Bragg gratings (FBGs) are used as the sensing elements – the strain induced by the patient’s respiration and cardiac activity cause a change of the Bragg wavelength. These changes can be accurately measured and monitored in the time domain. The respiratory and heart rate can be extracted by further processing of the measured signal by dedicated software. The gratings are organized in a network to maximize the effective sensing area. Each of the FBGs has a different Bragg wavelength so that they can be connected in series. The information from the sensors is read out using an interrogator based on an application specific photonic integrated circuit (ASPIC), designed and fabricated in an InP-based generic integration technology. The interrogator comprises a 36-channel arrayed waveguide grating wavelength demultiplexer, which outputs are connected to PIN photodiodes. Such a photonic circuit acts as a spectrometer and allows to reconstruct the reflection spectrum of many gratings simultaneously. An external superluminescent LED is used as the light source, however in the target configuration the source could be monolithically integrated with the interrogator. The Bragg gratings, the interrogator and the SLED are connected with each other using an optical circulator. Initial tests of the monitoring system have been performed using a single fiber Bragg grating as the strain sensor and a commercially available optoelectronic interrogator. The fiber with an inscribed FBG was mounted using an epoxy glue on a PMMA board and deployed under the patient. Two signals can be distinguished out of the measured waves. The first one, with strong and slowly-varying peaks, reflects the respiration of the patient. The second signal, characterized by low-intensity and fast-varying peaks is a result of the cardiac activity. No influence of the magnetic field of the MRI instrument on the sensing system has been observed. The first results have confirmed both the correctness of the approach and the applicability of the system to monitoring the patient’s physical condition during MRI diagnosis.

The measurement and characterization of micro-optical elements, systems and materials related to a variety of aspects like shape, displacement, deformation, strain / stresses, material constants, chemical composition etc. is a huge area which requires extended, multidisciplinary knowledge and a wide range of expensive instrumentation. The NEMO Centre for Measurement and Instrumentation includes twenty four institutes, whose joint expertise and capabilities do not only cover nearly all important measurement and characterization methods; they also comprise a big pool of commercial and internally developed instrumentation. In this paper we present the main tasks of this Centre. These tasks consist in e.g. providing benchmarks of the instrumentation and analysis software, providing an integrated pool of equipment for measurement and characterization of materials and components, identifying the gaps in measurement capabilities of existing equipment and providing guidance for development of new measurement methods and instrumentation, the development of proof-of principle demonstrators of novel measurement systems, and the development of numerical-experimental methods in collaboration with the virtual Centre for Modeling to support the development of novel micro-optics. In this paper we will also review the expertise of the NEMO partners in micro-optics measurement and characterization with the emphasis on aspects such as: microlens array testing, waveguide and fibre optics characterization, measurement of static and active microelements, determination of 3D refractive index distribution, subwavelength structure characterization, and shape monitoring and strain distribution testing in micro-optic packages. Also interesting issues connected with the definition of optimised measurement chains, data analysis and standardization of measurement procedures will be touched upon. Finally we will discuss the future structure of the Centre and its potential to provide virtual or on-site access to an electronic library which already contains a considerable amount of information on the large pool of instrumentation, jointly provided by the NEMO's partners.
