A Simple Oxygen Sensor Imaging Method with White Light-emitting Diode and Color Charge-coupled Device Camera

Abstract

Simultaneous acquisition of chemical information during photographic observation is highly advantageous in analyzing biological and industrial samples. Functional chemical imaging for this purpose, however, mostly requires specific light sources and optical filters compared to simple visual observation. in this research, a simple optical setting with familiar devices was employed for quantitative gas-phase oxygen imaging. a color charge-coupled device (CCD) camera and a broad-band white light-emitting diode (LED) were used to replace the blue LED and the optical filter. Commercial RedEyeTM oxygen-sensitive patches were used to verify this method. Several factors for image acquisition such as light source, optical filter, and color analysis method were evaluated in terms of sensitivity for quantitative oxygen imaging. a good sensitivity was obtained by a simple procedure of red color analysis of images taken with a color CCD camera under white illumination. Thissimple method has potential applications in multiple-analyte monitoring and simultaneous visual/chemical imaging of samples with general broad-band light sources and electronic color imaging devices.
