Compact LWIR Hyperspectral Polarimetric System Using AOTF Technology [UoH_FY06_015]

高光谱长波长红外（LWIR）成像传感器也可以具有利用偏振现象的能力。 总之，这可以使一种新的设计被用作定位隐藏物体和扰动地球的被动探测技术。 在较短的波长上，特别是在火星轨道卫星上，使用了一种可调谐的光谱成像滤光器。 使用这样的过滤器长波红外一直是材料研究的挑战。 该团队取得了重大进展，将允许使用该技术来演示溴化亚汞和硒化砷铊材料的基本光学和光谱材料。 该技术将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。 该原型将是可调的，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，从而能够更普遍地收集高光谱数据。 快速数据分析将提供快速检测地面扰动的反馈，例如在矿井或有毒物质中。 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。

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.
