    Abstract: Ensemble (N, M) de photodétecteurs pyroélectriques à film mince fabriqué comme une tranche Si. Un film mince (40) de PbTiO3 est déposé sur un pont (45) isolé thermiquement. Ledit pont (45) suspend le capteur PbTiO3 (40) au-dessus d'une cavité (70) obtenue de préférence par attaque de la tranche Si (10). L'isolation thermique améliorée augmente la sensibilité du capteur (33) à la radiation incidente. Le détecteur pyroélectrique (33) ainsi formé peut fonctionner efficacement à température ambiante.

    Abstract: Thermal radiation detection apparatus is provided comprising an array of pyroelectric detectors 1,2,3,4 in which compensation is provided for the effect of ambient temperature changes on the detector outputs and also for d.c. offsets which occur in source follower impedance converters 13 necessarily used with each detector. Single element detectors are used, the end pair of elements 3,4 being shielded from radiation and used as reference elements. Each element has a pair of diodes 11,12 connected in parallel in opposite sense to provide a d.c. path across the element. The reference element outputs are averaged 16,17,18 and fed via a high gain negative feedback loop 19 to the common connection 10 of all the elements. Offset voltages and element signals generated by ambient temperature changes are thereby compensated to the extent that the reference offsets and thermal voltages equal those of the active detector elements.
