Abstract
An IR thermometer design using multiple sensor outputs for correcting errors induced by variable probe placement in a patient's ear canal. One embodiment of the system uses two or more sensors to create varying fields of view of the tympanic membrane IR emissions. These discrete IR readings are then reconciled by on-board signal processing to provide an accurate, repeatable and relatively position independent temperature reading.
