ABSTRACT:
An infrared imaging system is disclosed which provides a two-dimensional visible image of the temperature profile of a radiating infrared source remotely located from the system. The invention is preferably implemented as a small hand-held instrument which can be held at a user's eye for sighting at a source of radiation and for viewing the temperature profile thereof. The system comprises an objective lens operative to focus an infrared image of a radiating source onto a surface of a liquid crystal structure, with the opposite surface of the structure being visually viewable by way of an eyepiece. The liquid crystal structure is biased preferably by a closed loop temperature control to be sensitive to an intended infrared spectrum of interest and to be substantially non-responsive to ambient temperatures.
