“…Next, to measure IR signals induced by temperature, an embedded-type thermometer probe (CH 2) of a FOT was also constructed. As an IR fiber, we selected a silver halide optical fiber (PIR 900/1000, Art Photonics, Berlin, Germany) that can serve as a sensing element and an IR waveguide at the same time [ 17 , 18 , 19 , 20 , 21 , 22 ]. Diameters are 0.9 mm for the core only and 1 mm including the cladding.…”

“…Next, in the cases of FOTs, they normally use a silver halide optical fiber as an infrared optical fiber (IR fiber) to measure temperature by transmitting IR signals emitted from a heat source [ 17 , 18 , 19 , 20 , 21 , 22 ]. As a non-contact temperature sensor, those based on IR fibers have been fabricated to use in examination or treatment rooms where magnetic resonance imaging (MRI) or radiofrequency ablation (RFA) devices are installed [ 20 , 21 ].…”

In this study, we have studied the effects of temperature and X-ray energy variations on the light output signals from two different fiber-optic sensors, a fiber-optic dosimeter (FOD) based on a BCF-12 as a plastic scintillating fiber (PSF) and a fiber-optic thermometer (FOT) using a silver halide optical fiber as an infrared optical fiber (IR fiber). During X-ray beam irradiation, the scintillating light and IR signals were measured simultaneously using a dosimeter probe of the FOD and a thermometer probe of the FOT. The probes were placed in a beaker with water on the center of a hotplate, under variation of the tube potential of a digital radiography system or the temperature of the water in the beaker. From the experimental results, in the case of the PSF, the scintillator light output at the given tube potential decreased as the temperature increased in the temperature range from 25 to 60 °C. We demonstrated that commonly used BCF-12 has a significant temperature dependence of −0.263 ± 0.028%/°C in the clinical temperature range. Next, in the case of the IR fiber, the intensity of the IR signal was almost uniform at each temperature regardless of the tube potential range from 50 to 150 kVp. Therefore, we also demonstrated that the X-ray beam with an energy range used in diagnostic radiology does not affect the IR signals transmitted via a silver halide optical fiber.

Keywords: fiber-optic temperature sensor, sensing probe, metal cap, infrared optical fiberIn this study, we developed a contact-type fiber-optic temperature sensor (CFOTS) for remote and real-time measurements of water temperature. The CFOTS consisted of a sensing probe, a transmitting infrared (IR) optical fiber, a light measuring device, and a laptop. The transmitting IR optical fiber was a polycrystalline infrared (PIR) fiber based on silver halides (AgCl:AgBr). The light-measuring device was a thermopile-type photodiode detector module. The sensing probes were metal caps fabricated from metals of high thermal conductivity: copper and aluminum. Several metal caps of different materials and different inner diameters (1.5, 2.5, and 3.5 mm) were prepared and characterized to identify the optimal material and size of the sensing probe in terms of its detection performance. The CFOTS measured the water temperature of a sample in an oil bath over a range of 30-70 °C. The experimental results showed that the copper metal cap with an inner diameter of 3.5 mm was the best water temperature sensor.

“…In recent years, the surface plasmon resonance (SPR)-based optical sensing of several quantities such as chemicals [1,2], temperature [3], pressure [4], force [5], environmental monitoring [6], optofluidic detection [7], food safety [8], and biological species [9,10], as illustrated in Figure 1 [11][12][13][14], has been proven to be advantageous. The optical fiber deployed in such sensors has replaced the traditional substrates for SPR sensors such as prisms, electrodes, etc.…”

Recent Advances in Plasmonic Sensor-Based Fiber Optic Probes for Biological Applications

The survey focuses on the most significant contributions in the field of fiber optic plasmonic sensors (FOPS) in recent years. FOPSs are plasmonic sensor-based fiber optic probes that use an optical field to measure the biological agents. Owing to their high sensitivity, high resolution, and low cost, FOPS turn out to be potential alternatives to conventional biological fiber optic sensors. FOPS use optical transduction mechanisms to enhance sensitivity and resolution. The optical transduction mechanisms of FOPS with different geometrical structures and the photonic properties of the geometries are discussed in detail. The studies of optical properties with a combination of suitable materials for testing the biosamples allow for diagnosing diseases in the medical field.
