Popis:	A new method for the detection of low oxygen concentration is proposed here. The system is based on the principle of enhancement of fluorescence yield of tetraphenylporphine (TPP) dye at λ=656 nm when excited by He-Cd laser at λ =441 nm in the presence of oxygen. The sensor head was fabricated by cladding the ARTON fiber core with the poly-4-methy1-1-pentene polymer matrix doped with TPP. The experimental results obtained indicate a good enhancement in the fluorescence when the sensor head is exposed to oxygen. The response was found to be linear and stable in the range of (100 ppm-1%) with the resolution of 0.01%. The sensor response was characterized by studying its response for change in temperature and is discussed below.
