Abstract
A facepiece assembly and a self-contained thermal imaging system comprises a facepiece that includes a front lens, an air inlet for receiving air under pressure, and an air outlet. The thermal imaging system includes a sensor lens connected to the front lens of the facepiece, and a rotating chopper wheel within the facepiece adjacent the sensor lens. A thermal imager sensor head produces digitized electronic data based upon an image projected onto the sensor head by the sensor lens and the rotating chopper wheel. An electronic processor is connected between the thermal imager sensor head and a heads-up display for processing the digitized electronic data and displaying the image on the heads-up display.
