Abstract:
An infrared thermometer comprising:at least one intensity transducer for detecting infrared radiation emitted by an area of a patient to be measured and for generating a corresponding measuring signal; a processing unit operatively associated with said transducer to receive said measuring signal and compute a corresponding temperature of the area to be measured; and control means for defining a correct positioning condition of said transducer at said control means comprising means for generating at least one primary light beam set to focus a predetermined primary figure substantially in correspondence with the area to be measured when said transducer is in a correct positioning condition at the pre-set distance from the area to be measured, a pre-set distance from the area to be measured, said control means comprising a matrix metric-based optical selector element downstream of said generating means and operating on said at least one primary light beam to determine the shape of said figure.
