Abstract

The application of an elliptical horn element for focusing radiation from relatively hot objects in the environment onto a thermal infrared sensor is presented. Theoretical calculations were used to determine the radiation concentration values in the horn element with the normal incidence of rays relative to the entrance section and a single reflection from the inner surface. The device with the horn element and thermal infrared sensor enables the detection of a person at a long distance (16 m) with a wide field of view in the horizontal direction (100°). The setup can operate both independently and in conjunction with other devices that monitor internal and external adjacent spaces.
