Abstract

Abstract Translated from German Pyrodetektor mit vorzugsweise PVDF-Folie, der aufgrund des Aufbaus des Sensors (2, 3) und aufgrund eines sphärischen bis sphärisch-parabolischen Spiegels (1, 101) für bewegungs- und richtungsselektives Detektieren verwendbar ist. Der Sensor (2) hat hierfür eine Anzahl in einem Bogen (K) angeordnete Einzel-Sensorelemente (30...36) und gegebenenfalls für Temperaturkompensation zugeordnete zusätzliche Elemente mit Elektroden (114). Der Sensor (2) ist ein ebenes Plättchen. Pyrodetector with preferably PVDF film, which can be used for movement and direction-selective detection due to the structure of the sensor (2, 3) and due to a spherical to spherical-parabolic mirror (1, 101). For this purpose, the sensor (2) has a number of individual sensor elements (30 ... 36) arranged in an arc (K) and, if appropriate, additional elements with electrodes (114) assigned for temperature compensation. The sensor (2) is a flat plate.
