1. A monolithic detection or infrared imaging structure comprising at least one electrically and thermally insulating polymer layer (114, 216, 218, 220), infrared sensors (102, 102a, 102b, 102c, 102d), which are insulated from one another and have a pyroelectric polymer film (104), whose face (109) in contact with the insulating layer (114) is equipped with two comb-shaped electrodes (106, 108), whose teeth (110, 112) are imbricated, the pyroelectric polymer film (104) being polarized (111) in a plane parallel to said face of the film in directions parallel (x) and perpendicular (y) to the teeth of the combs, an integrated circuit (116) having a face (134) in contact with the insulating layer (114) equipped with reading circuits (117, 117a, 117b, 117c, 117d) and electrical contact zones (130, 132, 222, 224, 226) completely traversing the insulating layer and connecting the electrodes (106, 108) of each sensor to a reading circuit (117, 117a, 117b, 117c, 117d).
