- Abstract
The suitability of single crystalline Lead Indium Niobate - Lead Magnesium Niobate - Lead Titanate (PIMNT) for application in IR flame detectors was studied and compared with state-of-the-art Lithium Tantalate (LTO). Due to their high pyroelectric coefficient, PIMNT-based sensors provide an increase of the specific detectivity in comparison to standard LTO-based detectors even at a very small element size. The evaluation shows good results in the design and the fabrication of the detectors for long-range and wide field of view ( FOV) flame detection.
