高工作温度碲镉汞p-on-n中波1024×768焦平面探测器
High operating temperature p-on-n HgCdTe MWIR 1024×768 FPA detector
摘要
Abstract
Increasing the operating temperature for infrared detectors is critical to reduce the size,weight and power of infrared(IR)systems.Such systems are essential to implement a compact and low-cost production of IR systems.For the Kunming Institute of Physics(KIP),HgCdTe standard p-on-n technology with indium doping and arsenic ion implantation technology has been optimized for many years and mid-wavelength IR(MWIR)de-tectors with excellent electro-optical performance were realized.This paper reports the latest results of the MWIR focal plane array(FPA)detector with a high operating temperature(HOT).Performances of the 1024×768@10 µm pitch MW detector working above 150 K were presented.The detector presenting a cut-off wavelength above 4.97 µm at 150 K has been developed.The noise-equivalent temperature difference(NETD),dark current and operability at different operating temperatures were attained.Additionally,the IR image taken with the MWIR HgCdTe-based FPA and processed at an operating temperature of 150 K was presented and retained an operability of 99.4%.关键词
