Abstract
A device for imaging and delivering spectroscopic information comprises an objective (1), an image sensor (2) and an optical component (3) having a spectral differentiation function. The optical component having a spectral differentiation function modifies the image of a point in different ways for at least two colours, so that a form of the image of the point delivers spectroscopic information that appears directly in the image as captured by the image sensor. Such device may be used in a detection and/or surveillance system, which then possesses a lower probability of false alarm value.
