Pyroelectric IR sensor |
摘要 |
A pyroelectric IR sensor equipped with a chopper for opening and closing a shielding plate so that infrared rays emitted from an object are allowed to be incident onto a pyroelectric sensor unit and intercepted therefrom, and having a structure capable of providing a large shielding width for the shielding plate without enlarging the chopper. Piezoelectric members are formed on a thin elastic sheet composed of a planar sheet having a tip to which a shielding plate is attached, except for a partial region which functions to magnify oscillations for enlarging displacement of the shielding plate.
