Abstract:
A long period grating fiber optic sensor coated
with hemoglobin is used to detect dissolved oxygen.
The sensitivity of this sensor to the ratio of dissolved carbon
dioxide to dissolved oxygen is demonstrated via the conversion of
carboxyhemoglobin to oxyhemoglobin on the sensor surface. The
sensor shows good repeatability with a %CV of less than 1% for
carboxyhemoglobin and oxyhemoglobin states with no
measurable drift or hysteresis.
