"Optical sensing in medical diagnosis and chemical analysis using optoelectronic devices is a growing technology since it offers many advantages including real time analysis, remote sensing capability and low cost approach. This thesis demonstrates that an optical sensing platform utilizing optical mouse, the ubiquitous optoelectronic computer peripheral, can be used in quantitative oxygen and pH analysis.
Work in the first paper includes the use of optical mice for fluorescence intensity imaging of commercial oxygen patch. This involves gray color intensity analysis of filtered images to determine the gaseous oxygen level.
In the second paper, the optical mice is used to measure light absorption and reflection of commercial pH test strips. This sensing scheme is based on detecting the colorimetric change in response of pH test strips to different pH values. The linearity and sensitivity was comparable to those of traditional spectrometric measurement.
This novel, cost-effective approach demonstrates potential application of using optical mouse for simultaneous monitoring and imaging of biological or chemical samples. Therefore, quantitative chemical analysis is possible with even very common computer peripheral devices with the aid of commercial sensor strips"--Abstract, page iv.
