我们描述了一种专为机器人和无人机应用而开发的新型 InGaAs SWIR 微型相机。该相机体积小于 27 cm3，重量小于 100 g，功耗小于 1.4 W。相机在室温下使用焦平面阵列工作，对 0.9 μm 至 1.7 μm SWIR 波段敏感，探测灵敏度 D* 大于（论文中提供的公式）。 InGaAs 焦平面阵列具有 320x256 像素，间距为 25 μm。它具有快照模式集成，最小曝光时间为 500 ns，非常适合全固态距离选通成像。全帧读出速率大于每秒400帧。内置窗口功能非常灵活，多达 8 个任意形状的感兴趣区域可以位于成像仪上的任何位置（包括重叠）。例如，8 个 64 x 64 感兴趣区域 (ROI) 的读取速度可以超过每秒 1000 帧，单个 64 x 64 ROI 的读取速度可以超过每秒 5000 帧，从而实现高速目标采集和跟踪应用。
We describe a new InGaAs SWIR microcamera developed for robotic and UAV applications. The camera has a volume less than 27 cm3, weighs less than 100 g, and consumes less than 1.4 W. The camera operates with the focal plane array at room temperature and is sensitive to the 0.9 μm to 1.7 μm SWIR band with a detectivity, D*, greater than (formula available in paper). The InGaAs focal plane array has 320x256 pixels on a 25 μm pitch. It features snapshot-mode integration with a minimum exposure time of 500 ns making it ideally suited for all-solid-state range-gated imaging. The full-frame readout rate is greater than 400 frames per second. The built-in windowing feature is highly flexible with as many as 8 arbitrarily shaped regions-of-interest can be located anywhere (including overlapping) on the imager. Eight 64 x 64 regions of interest (ROIs), for example, can be read out faster than 1000 frames per second with a single 64 x 64 ROI read out faster than 5000 frames per second enabling high speed target acquisition and tracking applications.
