摘　　要：建立和完善了电流模式Pb(In_(1/2)Nb_(1/2))O_(3)-Pb(Mg_(1/3)Nb_(2/3))O_(3)-PbTiO_(3)(PI-MNT)热释电红外探测器的理论模型(单通道和并联补偿型)以及微音噪声模型。利用理论模型进行了仿真模拟,然后设计和制备了一种单通道和两种补偿型(灵敏元分隔型和一体型)PIMNT热释电红外探测器。测试并比较了这三种探测器的响应率RV、噪声u_(n)、比探测率D^(*)以及微音噪声u_(vib)。结果表明,与单通道PIMNT红外探测器相比,补偿型红外探测器的探测能力虽然略有下降,但抗干扰能力却得到了极大提高。The theoretical model(single-channel and parallel compensation type)and the microphonic noise model of the Pb(In_(1/2)Nb_(1/2))O_(3)-Pb(Mg_(1/3)Nb_(2/3))O_(3)-PbTiO_(3)(PIMNT)pyroelectric infrared detectors with current mode are established and improved.The theoretical model is used for simulation,and a single-channel and two compensated(sensitive element separated and integrated)PIMNT pyroelectric infrared detectors are designed and prepared.The responsivity(RV),noise(u_(n)),specific detectivity(D^(*))and microphonic noise(u_(vib))of these three detectors are tested and compared.The results show that,compared with the single-channel PIMNT infrared detectors,the detection ability of the compensated infrared detectors is slightly reduced,but the anti-jamming ability has been greatly improved.
