The detection of a coincident bright X-ray burst represents the first observed multiwavelength counterpart of an FRB. However, the search for similar emission at optical wavelengths has been hampered by the high inferred extinction on the line of sight. Here, we present results from the first search for second-timescale emission from the source at near-infrared (NIR) wavelengths using the Palomar Gattini-IR observing system in the J band, enabled by a novel detector readout mode that allows short exposure times of ?0.84 s with 99.9% observing efficiency. With a total observing time of ?12 hr (?47,728 images) during its 2020 outburst, we place median 3Ҡlimits on the second-timescale NIR fluence of ?18 Jy ms (13.1 AB mag). The corresponding extinction-corrected limit is ?125 Jy ms for an estimated extinction of AJ = 2.0 mag. Our observations were sensitive enough to easily detect an NIR counterpart of FRB 200428 if the NIR emission falls on the same power law as observed across its radio to X-ray spectrum. We report nondetection limits from epochs of four simultaneous X-ray bursts detected by the Insight-HXMT and NuSTAR telescopes during our observations. These limits provide the most stringent constraints to date on fluence of flares at 1014 Hz, and constrain the fluence ratio of the NIR emission to coincident X-ray bursts to RNIR ? 0.025 (fluence index ?0.35).   The experimental study about laser-induced dizziness effect of medium-wave infrared seeker which based on image processing 期刊论文  OAI收割 Journal of Visual Communication and Image Representation, 2019, 卷号: 59, 页码: 401-406 作者:  Z.B.Chen;  K.Shi;  N.Chen;  L.Shi;  X.Y.Zhuang   |  收藏  |  浏览/下载：63/0  |  提交时间：2020/08/24 Image processing,Laser dizziness interference,Medium wave infrared,detector,Photoelectric interference,Computer Science   Polarization-selective dual-band infrared plasmonic absorber based on sub-wavelength gaps 期刊论文  OAI收割 Optics Communications, 2019, 卷号: 446, 页码: 156-161 作者:  H.H.Yu;  Z.Z.Liang;  D.J.Meng;  J.Tao;  J.Q.Liang   |  收藏  |  浏览/下载：19/0  |  提交时间：2020/08/24 Polarization-sensitive,Dual-band,Plasmonic absorber,Uncooled infrared,detector,metamaterial,,division,Optics   Calibration technique of spectral radiation for an infrared trap detector 期刊论文  OAI收割 JOURNAL OF INFRARED AND MILLIMETER WAVES, 2018, 卷号: 37, 期号: 5, 页码: 572-577 作者:  Zhang Lei;  Lin Zhi-Qiang   |  收藏  |  浏览/下载：52/0  |  提交时间：2019/12/25 infrared radiometric calibration  infrared trap detector  cryogenic absolute radiometer  uncertainty   Design of a near-infrared sky brightness monitor and field measurement at the Ngari Observatory, Tibet 期刊论文  OAI收割 JOURNAL OF ASTRONOMICAL TELESCOPES INSTRUMENTS AND SYSTEMS, 2018, 卷号: 4, 期号: 4, 页码: 13 作者:  Tang, Qi-Jie   |  收藏  |  浏览/下载：18/0  |  提交时间：2020/03/10 site testing  infrared sky brightness  InGaAs detector   Mo-al co-doped vo2(b) thin films: cvd synthesis, thermal sensitive properties, synchrotron radiation photoelectron and absorption spectroscopy study 期刊论文  iSwitch采集 Journal of alloys and compounds, 2018, 卷号: 745, 页码: 247-255 作者:  Guo, Beibei;  Wan, Dongyun;  Wang, Jiaou;  Zhu, Sixv;  Luo, Hongjie 收藏  |  浏览/下载：192/0  |  提交时间：2019/04/23 Vo2(b) thin films  Uncooled infrared (ir) detector  Synergetic improvement  Mo-al co-doping  Synchrotron radiation study
