ABSTRACT:
A self-check electronic system for infra-red observation includes a hood having a first port transparent to infra-red radiation and a second port which is reflected through infra-red radiation and the hood can be rotated so that the second port is perpendicular to an infra-red detector optical sighting line so that a self-checking operation determining whether the optical system is aligned may be performed.
