    • A totally integrated thermal imaging system having a dewar housing (12) including imaging optics, a scanning mirror (16) and a curved detector array (20). The imaging optics constitute a meniscus lens (14) and a spherical focusing mirror (18). The scanning mirror (16) scans the image, and the spherical mirror (18) focuses the scanned image onto the detector array (20). The meniscus lens (14) advantageously corrects aberrations. A detector support (26) provides access for cryogenic cooling of the detector (20), and individual cold shielding of the detector elements is made possible by the telecentricity of the optics. Processing electronics, at least a portion of which may also be disposed on the detector support (26), process the detector signals to display an image. The integrated structure advantageously eliminates any need for separate scanner, imager, detector dewar and electronics modules.
    • 一种完全集成的热成像系统,其具有包括成像光学元件的杜瓦壳体(12),扫描镜(16)和弯曲检测器阵列(20)。 成像光学元件构成弯月透镜(14)和球面聚焦镜(18)。 扫描镜(16)扫描图像,球面镜(18)将扫描图像聚焦到检测器阵列(20)上。 弯月透镜(14)有利地校正像差。 检测器支撑件(26)提供了用于检测器(20)的低温冷却的通路,并且通过光学器件的远心性使检测器元件的各个冷屏蔽成为可能。 处理电子设备(其至少一部分也可以设置在检测器支撑件上)处理检测器信号以显示图像。 集成结构有利地消除了对单独的扫描仪,成像器,检测器杜瓦瓶和电子模块的任何需要。
