Measurement and improvement of characteristics using optical fiber temperature sensors at cryogenic temperatures

“…Temperature measuring tests were performed by cooling a room to about 10K, producing a satisfactory level of reproducibility. Trials revealed however that the sensitivity of wavelength shift to temperature fell at temperatures below 50K, although it was possible to restore sensitivity by applying coating [14][15].…”

Fiber bending and temperature loss mechanisms in plastic optical fibers are reported.A simple arrangement is used to monitor the fiber bending and temperature by output power variation. Powers in the fibers in bend‐free situation at room temperature and under rolling deforming force at different water bath temperatures (20–60°C) are measured and compared. Reported arrangements can be used as a temperature sensor. © 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:82–86, 2013; View this article online at wileyonlinelibrary.com.

“…Optical fibers have received a great deal of attention because of many advantages such as light‐weight, low‐cost, ease of handling, and immunity from electromagnetic noise. Optical fiber sensors demonstrated over the past decades were intended for the detection of physical and chemical properties such as strains [1, 2], temperatures [3, 4], pH [5, 6], gas [7] and so on. In particular, there were many reports of fiber optic relative humidity sensors [8–11].…”

An optical lensed fiber for detecting respiration condition in the vicinity of nose has been proposed and been demonstrated to work as a breath sensor. For simple preparation and larger sensing area, a piece of about quarter‐pitch of an optical gradient index fiber (GIF) tip was spliced to the end of a single mode fiber. The sensing principle is based on the change of back reflection intensity caused by attachment of water molecules on the GIF tip during respiration. The experimental results showed that this breath sensor operated with a good sensitivity and a real‐time respiration monitor was presented. In terms of the tiny size and light weight, the optical lensed fiber breath sensor is potential for the application of monitoring breathing condition in hospital and in home care. © 2012 Wiley Periodicals, Inc.
