Method for the surveyance of an object space
First Claim
1. A method of monitoring a target space, characterised by projecting thermal infrared radiation of the target space by means of an infrared lens on to at least one infrared sensitive detector, forming an electrical signal sequence by constant scanning and passing this signal sequence in a specific colour directly to a colour TV and delayed and in another colour to the same monitor as an image of the object.

Abstract
In order to clearly reveal modifications, even small alterations occurring in a controlled object space (1), the thermal infrared radiation of the object space (1) is represented by means of an infrared objective (2) on two different infrared detectors (3, 4; 3'"'"', 4'"'"') and having each different spectral selectivity characteristics. Those two representations are serially scanned to form two sequences of electrical signals (5, 5'"'"'). One of those signal sequences (5'"'"') is reproduced on a television monitor (7) directly in a predetermined color (8'"'"') and the reproduction of the other signal sequence (5) is delayed and is effected in another color (9'"'"').
