ABSTRACT
Chirped Fiber Bragg Grating (CFBG) has been widely applied in optics for temperature measurement characteristics, such the temperature of the human body. CFBG has the advantages of its grating structure, such as low cost, small size, real-time response, high accuracy, high sensitivity, and immunity to electromagnetic interference. Temperature is one of the important physical parameters in explaining a person's health condition and the condition of an environment. This study aims to analyze the heat distribution pattern of the human body. This research uses the paper tape method as a medium attached to the CFBG grating fiber connected to the Optical Sensing Interrogator tool at the points of the human body object. The parts of the human body measurement points are the forehead, neck, hand folds, and foot folds. Changes in temperature to the Bragg wavelength will determine the effect of infrared intensity on temperature and the effect of infrared intensity on the Bragg wavelength and temperature on reflectivity at the measurement point. The results showed that the largest intensity value of the CFBG sensor is -5.4900 dBm with a temperature of 36.90C found on the neck with 90% reflectivity. While the smallest intensity value of the CFBG sensor is -15.4050 dBm with a temperature of 35.80C found in the folds of the legs with a reflectivity of 10% for a wavelength source of 1550 nm. The largest wavelength value of the CFBG sensor is 1550.6357 nm at a temperature of 36.90C found at the neck with 90% reflectivity and the smallest wavelength value of the CFBG sensor is 1549.9474 nm at a temperature of 35.80C with 10% reflectivity for a 1550 nm wavelength source. Infrared intensity to wavelength is directly proportional to the increase in temperature, the higher the temperature. The higher the change in intensity and wavelength. The sensitivity and accuracy of the data generated by the CFBG sensor are significant so that it has the potential to be developed.
