<p>The device has a spectral infrared radiation separation element (3) for differently modifying direction of a radiation portion according to wavelength for a fixed set of wavelengths. The separation element is arranged with respect to an objective (1) and to a matrix detector (2) to produce a reference image (P0) and a secondary image (P1) on detection surface of the detector. The secondary image of a target is located at distance from the reference image, which depends on the wavelength of the infrared radiation from the target. Independent claims are also included for the following: (1) a detection head for a directed infrared counter-measure system comprising a detecting device (2) a directed infrared counter-measure system comprising a detection head.</p> |
