Abstract

A modulation system for the phase-resolved two-dimensional fluorescence phase imaging of a planar optical oxygen sensor is presented. The proposed system is based on the phase fluorometry technique and uses the four-frame integrating-bucket method. Integrating buckets with multiple frames are achieved using a complex programmable logic device to provide an external trigger to the charge coupled device (CCD). The oxygen-sensitive film is based on microporous film prepared using a sol-gel process with a Pt(II) complex, platinum tetrakis pentafluorophenyl porphine (PtTFPP); the film can be efficiently excited by a laser diode with a central wavelength of 405 nm. The experiment results show that the maximum phase difference between 0% and 100% gaseous oxygen is 22°. The 2D full-filed O2 distribution imaging was found to be the most sensitive between 0% and 20% O2. The combination of optical sensor technology and phase-resolved imaging allows the determination of the distribution of chemical or physical parameters in heterogeneous systems, making the proposed system a powerful testing tool for screening and mapping applications.
