湖滨低温电子学公司收到了国防部SBIR / STTR赠款项目的标题为:光纤温度传感器长时间低温热路径。抽象给这个项目如下:这SBIR第一阶段建议地址灾害防治,高温超导输电线路、电动机、发电机和其他专用设备,正在部署。即使高温超导体可以操作77 k或更高,大部分设备操作在较低温度下获得安全系数,以防止过热或磁磁场诱导淬火。超导体的长度从几十米到可能涉及许多公里。如果开发热点,导致导体迅速恢复其电阻状态,增加局部加热和传播的错。这将导致迅速耗散的能量存储在导体或线圈,与破坏的一个重要概率导体如果淬火没有检测到。光纤温度传感器存在机会检测热点密集点沿任意长度的超导体为了安全地关闭系统损害发生之前。这些传感器都是介质,使其安全甚至非常高电压电力系统,和许多感应点,尽可能几厘米到一米,可以多路复用单个光纤,极大地简化了直通的需求相比,电子传感器。湖滨低温电子学公司收到了国防部SBIR / STTR赠款项目的标题为:Long-to-Very-Long-Wavelength空间红外探测器红外带通滤光片。抽象给这个项目如下:这个阶段我SBIR的建议要求创新的传感器解决方案来提高传感器的战略空间。 One route of improvement is selective band-pass filtering of radiation before it reaches the detector. Such filtering can improve detection by blocking out-of-band interferences and allowing transmission of the desired spectral components. Filtering can improve a cheaper detector with a broader detection profile into a high performance detector. Filtering can also improve signal-to-noise of a detector by eliminating out-of-band radiation from reaching the detector and causing spurious signal or A/D saturation. Comparable band-pass filters in the mid-infrared are typically thick multilayer dielectrics subject to poor adhesion between layers, thermal mismatch stress, or moisture sensitivity which can lead to destructive delamination. The innovative very-long-wavelength-region band-pass filter design proposed here has high transmission, can tolerate cryogenic temperatures, ionizing radiation and vibration making them launch-capable. The 2mm-thin proposed band-pass filter allows insertion into tight spaces. Lake Shore has demonstrated prototype band-pass filters with center bands from 14 - 25 microns in the infrared spectrum. By using innovative fabrication, it will be possible to extend this range down to the long-wavelength-infrared region. New IR detectors, developed in-tandem with Lake Shore band-pass filters can produce a high-performance solution for MDA applications.
