Abstract
A thermal camera is mounted within a helmet and is arranged such that the optical path in free space from its output is wholly within the volume defined by the helmet and the helmet faceplate. The output iminges on a concave mirror/lens combination located below the wearer's sightline. The arrangement is particularly suitable for fire fighting and search and rescue applications.
