    摘要： The infrared detector comprises two light receiving elements connected in series in such directions as to oppose the orientations of polarization thereof to each other, a compensating element connected to the connection point between the two light receiving elements in such a direction as to oppose the orientation thereof to those of the two light receiving elements, and has sensitivities to outputs produced by vibration and temperature variation substantially equivalent to the sums of the sensitivities of the two light receiving elements to outputs produced by vibration and temperature variation, and two FETs having gates connected to the two light receiving elements respectively and to the compensating elements through resistors or diodes, these component members being accommodated in a cylindrical case shielding these members optically and electromagnetically. Arranged on the cylindrical case are two windows for allowing light to be incident on the two light receiving elements and a light interrupting wall for preventing light emitted from a single object from being incident simultaneously on the two light receiving elements.

    摘要： A pyroelectric infrared detector for use in, for example, an intrusion alarming system has a pyroelectric element, a FET for picking up the output of the pyroelectric element, a capacitor connected in parallel to the pyroelectric element, and other circuit parts. These constituent parts are integrally packed in a package.
