<p><P>PROBLEM TO BE SOLVED: To provide an infrared radiation detector enabling quick detection at the edge of the field of view and high-sensitivity detection at the center of the field of view. <P>SOLUTION: This detector comprises an assembly of elementary sensors capable of detecting the radiation. This assembly comprises at least two separate detection areas: a first detection area comprises elementary sensors having first thermal time constants, and a second detection area (46-49) comprises elementary sensors having second thermal time constants which are smaller than those of the first thermal time constants. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
