Abstract
A medical sensor may be adapted to prevent unwanted light and electrical interference from corrupting physiological measurements. Sensors are provided with features that reduce the amount of outside light or shunted light that impinge the detecting elements of the sensor. The sensor is adapted to reduce crosstalk between electrical signals, increasing the accuracy of measurements. The sensor is also adapted to reduce the effect of outside light or shunted light on pulse oximetry measurements.
