An apparatus for measuring temperature comprises a noncontact temperature
measurement device situated at a first location. The device includes a
sensor operative to collect radiant energy emanated from a target.
Circuitry associated with the sensor produces a digital temperature
signal containing temperature data regarding the target. A video camera
produces a digital video signal containing video data of the target. A
processor receives the digital temperature signal and the digital video
signal and produces a combined digital signal for transmission to a
second location. The combined digital signal contains both the
temperature data and the video data. A computer situated at the second
location receives the combined digital signal and separates the
temperature data from the video data. Preferably, the computer includes a
display having two windows on which the temperature data and the video
data are respectively shown.
