A hyperspectral long wavelength infrared (LWIR) imaging sensor may have the ability to utilize polarization phenomena as well. Together, this could enable a new design to be used as a passive detection technique for locating concealed objects and disturbed earth. At shorter wavelengths, a tunable spectral imaging filter has been used, particularly in the Mars orbit satellite. Using such a filter for LWIR has been an materials research challenge. The team has made a significant advance that will permit this technology to be used to demonstrate the basic optical and spectral materials of the mercurous bromide and thallium arsenic selenide materials. The technology should enable the production of very compact and lightweight sensors, capable of being carried or used as an unattended ground sensor. The prototype would be tunable, so that the operator could select the preferred frequency and bandwidth specific to the use of the sensor, thereby enabling a ore generalized collection of hyperspectral data. Rapid data analysis wil provide feedback of rapid detection of ground disturbances, such as in mines, or noxious materials. The research projects will engage students in pushing this engineering and data analysis frontier.

高光谱长波红外（LWIR）成像传感器也可能具有利用偏振现象的能力。总之，这可以使一种新的设计成为一种被动探测技术，用于定位隐藏物体和扰动地球。在较短的波长，可调光谱成像滤波器已被使用，特别是在火星轨道卫星。使用这样的低波长红外滤波器一直是材料研究的一个挑战。该团队已经取得了重大进展，这将使这项技术能够用于展示溴化汞和砷硒化铊材料的基本光学和光谱材料。该技术应该能够生产非常紧凑和轻便的传感器，能够作为无人值守的地面传感器携带或使用。原型将是可调的，因此操作员可以选择特定于传感器使用的首选频率和带宽，从而实现更广泛的高光谱数据收集。快速数据分析将提供快速探测地面扰动的反馈，例如在矿山或有毒物质中。这些研究项目将使学生参与推动这一工程和数据分析前沿。
