ABSTRACT:
Forward looking infra-red apparatus including an enclosure, a reflector riving infra-red energy from a field of view and a receiver, which receives the infra-red energy from the reflector and provides an output indication of an infra-red image of the field of view, wherein the receiver is hermetically sealed within the enclosure and the reflector is disposed outside of the enclosure and is foldably mounted with respect thereto so as to assume a first orientation when the apparatus is in operation and a second folded and more compact orientation than the first orientation when the apparatus is not in use.
