Equipments Used to Measure Body Temperature

2.0K
Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

IR Spectrometers

3.3K
There are two main infrared (IR) spectrophotometers: dispersive IR spectrometers and Fourier transform infrared (FTIR) spectrometers. In a dispersive IR spectrometer, a beam of infrared radiation produced by a hot wire is divided into two parallel equal-intensity beams using mirrors. One beam passes through the sample, while another is a reference beam. The beams then move through the monochromator, which separates the radiations into a continuous spectrum of different frequencies. The...

Area of Science:

  • Optics and Photonics
  • Materials Science
  • Metrology

Background:

  • Traditional resistance thermometry faces limitations in certain applications.
  • Photonic sensors, specifically Fiber Bragg Gratings (FBGs), are emerging as viable alternatives.
  • FBGs offer potential advantages in sensitivity and robustness for temperature measurement.

Purpose of the Study:

  • To investigate the thermal response of Fiber Bragg Gratings (FBGs) within a specific temperature range.
  • To quantify the measurement uncertainty associated with FBG temperature sensing.
  • To identify key factors contributing to the overall uncertainty in FBG thermometry.

Main Methods:

  • Experimental characterization of FBG sensors.
  • Thermal cycling across a temperature range of 233 K to 393 K.
  • Operation within a hermetically sealed, dry Argon environment to control ambient conditions.

Main Results:

  • FBG devices demonstrated a clear quadratic dependence on temperature.
  • Expanded uncertainties (k=2) for temperature measurements were determined to be approximately 500 mK.
  • Dominant sources of uncertainty were identified as peak center fitting and thermal aging of polyimide-coated fibers.

Conclusions:

  • FBGs provide a highly accurate photonic temperature sensing solution.
  • The quadratic thermal response is well-defined under controlled environmental conditions.
  • Minimizing uncertainties in peak fitting and addressing fiber aging are crucial for optimizing FBG sensor performance.
