PYROELECTRIC RELAXOR FERROELECTRIC INFRARED DETECTOR

WIPO Patent Application WO/2015/172585

A1

Provided is a pyroelectric relaxor ferroelectric infrared detector. The detector comprises: a base provided with a pin; a casing having one or a plurality of windows, the casing being packaged together with the base to form an accommodating space; a sensitive element chip arranged within the accommodating space; electrodes respectively arranged on an upper surface and a lower surface of a pyroelectric relaxor ferroelectric single crystal sensitive element; an absorption layer covering the upper surface of the single crystal sensitive element; a frame supporting the single crystal sensitive element; an amplification circuit using a voltage mode or a current mode. An upper electrode arranged on the upper surface is a single electrode, and a lower electrode arranged on the lower surface comprises a left electrode and a right electrode separated from one another. The left electrode and the right electrode are not connected to one another to form the lower electrode as a divided electrode. Therefore, dielectric noise of device preparation is reduced, and the response rate and specific detectivity of the detector is increased.
