Abstract
A pyroelectric detector (20) includes a focal plane array (22) having a plurality of image sensors configured to convert electromagnetic energy into an electrical signal, and a memory module (24) coupled to the focal plane array. The focal plane array and the memory module are positioned on a common substrate platform (62).
Claims19
A pyroelectric detector system comprising:
- a substrate platform;
- a focal plane array integrated into the substrate platform, the focal plane array including a plurality of image sensors configured to convert electromagnetic radiation into an electrical signal;
- and
- a memory module integrated into the substrate platform and coupled to the focal plane array.

A method of operating a pyroelectric detector system for at least one of presence detection of a human, detection of a hot object, and counting of humans, the method comprising:
- operating a focal plane array in a sleep mode utilizing a first excitation current, and wherein the focal plane array, a memory module and a processor are mounted on a common substrate platform;
- sensing gross motion by the focal plane array;
- and
- operating the focal plane array in a full capability mode at a second excitation current that is greater than the first excitation current.
