Abstract:
1. A device for measuring the core temperature of a subject animal or human, based on thermal emissions from the subject's eye, comprising: a sensor unit having at least an optical modulator, a detector and a temperature sensor; wherein the sensor unit is contained within a housing configured to provide thermal isolation of its internal elements; a lens for receiving the thermal emissions from the subject's eye and directing the thermal emissions to the sensor unit via an aperture; a shutter between the lens and the sensor unit, normally in a closed position such that it blocks the aperture and operable to open while the thermal emissions are being measured; the optical modulator operable to modulate the amount of the thermal emissions that reach the detector while the thermal emissions are being measured; the detector operable to detect only selected wavelengths of thermal emissions from the eyeball of the subject and to generate a signal corresponding to the emissions; the temperature sensor operable to measure temperature inside the sensor unit proximate the aperture; wherein the sensor unit is non contacting to the eyeball; a data processing unit for converting the signal to raw temperature data and for determining core temperature data based on the raw temperature data and based on temperature data provided by the thermometer; and a display for displaying the core temperature data.
