Abstract: A motion sensor has at least two tiers of monitored volumes that are offset from each other. Electromagnetic radiation, such as infrared light, is directed from the monitored volumes onto at least two sets of detector elements having separate outputs on a pyroelectric substrate of an infrared detector. As a warm object, such as a human or an animal, moves through the monitored volumes, the warmth from the object causes the voltage on the outputs of the infrared detector to change. The resultant waveforms are compared and if the two waveforms have a phase relationship corresponding to a critical phase angle that is based on the pitch of the monitored volumes and the offset between the tiers of monitored volumes, an animal-immune motion indication is generated.

Abstract: A detecting element has an absorbing section where a temperature rises according to an amount of electromagnetic waves which are absorbed and a detecting section where characteristics change according to an amount of heat which is transmitted from the absorbing section. A method for manufacturing the detecting element includes: forming the detecting section on a substrate; forming a protective film which covers the detecting section; forming a hollow space portion in a region which overlaps with the detecting section of the substrate in a planar view after the forming of the protective film; and forming the absorbing section by applying a liquid body, which contains a material constituting the absorbing section, in a region on the protective film on an opposite side from the detection section, which overlaps with the detecting section in a planar view, and solidifying the liquid body after the forming of the hollow space portion.

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.

Abstract: The capacitive bolometer comprises a detection capacitor having a first-order phase transistion ferroelectric material between two electrodes. The detection capacitor operates during a detection step and a subsequent readout step. During the detection step, a preselected electric field is applied to the detection capacitor to maximize its sensitivity to temperature. A second electric field is applied to the capacitor during the readout step in order to increase responsivity of the detection cell. The detection cells according to the invention can be assembled into disclosed detection arrays.
