Request InfoArmstrong Optical Ltd.A sensing system for the detection of infectious diseases, such as SARS and the avian influenza, has been introduced by Armstrong Optical Ltd. Designed to inspect moving crowds of people for those with fever symptoms, the IR230 consists of a high-resolution visible camera, image processing software and an uncooled focal plane array detector with a temperature sensitivity of <0.1 °C. It can take images and make temperature measurements from as far away as 50 to 100 m. A cursor tracks the object with the highest temperature in the field of view.
