Optical Dissolved Oxygen Sensors
Optical dissolved oxygen sensors measure the interaction between oxygen and certain luminescent dyes. When exposed to blue light, these dyes become excited (electrons gaining energy) and emit light as the electrons return to to their normal energy state. When dissolved oxygen is present, the returned wavelengths are limited or altered due to oxygen molecules interacting with the dye. The measured effect is inversely proportional to the partial pressure of oxygen. While some of these optical DO sensors are called fluorescent sensors, this terminology is technically incorrect. These sensors emit blue light, not ultraviolet light, and are properly known as optical or luminescent DO sensors. Optical dissolved oxygen sensors can measure either the intensity or the lifetime of the luminescence, as oxygen affects both.
An optical DO sensor consists of a semi-permeable membrane, sensing element, light-emitting diode (LED) and photodetector. The sensing element contains a luminescent dye that is immobilized in sol-gel, xerogel or another matrix. The dye reacts when exposed to the blue light emitted by the LED. Some sensors will also emit a red light as a reference to ensure accuracy. This red light will not cause luminescence, but simply be reflected by the dye. The intensity and luminescence lifetime of the dye when exposed to blue light is dependent on the amount of dissolved oxygen in the water sample. As oxygen crosses the membrane, it interacts with the dye, limiting the intensity and lifetime of the luminescence. The intensity or lifetime of the returned luminescence is measured by a photodetector, and can be used to calculate the dissolved oxygen concentration.
