超导红外技术的发展概况及应用前景

Development of High T_c Superconducting Infrared Detector and Prospect

一般半导体红外探测器的性能只对一定的波长范围有响应，而超导红外探测器就不存在这一缺点，它在紫外、红外、亚毫米波、微波波段都能保持高灵敏度和极快的响应速度。８０年代中后期，单元超导红外探测器的ＮＥＰ已达１０－１２ＷＨＺ１／２。近１０多年来，超导红外探测器已经实现了从单元到线列、面阵的过渡，９０年代初，８×８元和４×１２８元面阵已经成熟，更大规模的面阵也在试验中。另外，在超导红外焦平面列阵中已采用了Ａ／Ｄ转换。随着高Ｔｃ超导红外技术及相关技术的发展，预计不久即可在军事和其它领域实现许多新的应用。

Semiconducaor IR detectors can only response to certain waveband,but superconducting Infrared Detector doesn't Have this limit,which exhibits high sensitivity and extra tesponse from UV,IR,Submillimeter,millimeter to microwave.In the middle of 80's,the NEP of single element Superconducting Infrared Detector reached10-12. In last An more years, Superconducting Infrared Detector has passed over the steps over the steps from single element,linear array to focal plane array.At the beginning of 90's, 8×8 and 4×128 chips have already been made out successfully.Larger FPA is in developing.It can be poded that with the rapid deVelopment of Superconducting infrared technology and telated subject,this detectors will find broad application in millitary and other areas.
