Title:
PYROELECTRIC INFRARED DETECTION DEVICE
Document Type and Number:
Japanese Patent JP2011112508
Kind Code:
A
Abstract:
To solve a problem that, since mounting members are small in number, and a heat capacity is small relative to a capacity in a pyroelectric infrared detector, when an abrupt temperature change is caused, a heat influence on a pyroelectric element is large, and a drift of an output signal has a limit to the temperature change.
In order to enlarge the heat capacity, to reduce the heat influence on the pyroelectric element even if the abrupt temperature change is caused, and to suppress the drift of the output signal to the temperature change, a two-storied substrate structure having two built-in substrates in the pyroelectric infrared detector is adopted.
