摘要:
Embodiments of the invention describe solutions directed towards having a single camera capable of capturing high speed laser return pulses for a target, as well as provide imaging information on the background of the target. This capability is enabled by having a read-out integrated circuit (ROIC) capable of extracting both types of information from a pixel of a focal plane array (FPA). Embodiments of the invention describe an ROIC topology that allows for the ability to distinguish between high frequency and low frequency signal paths, and provide supporting circuitry to process the two paths separately. One path may integrate the low frequency background scene to provide a high fidelity image of the scene. The second path may process high frequency noise and multiple laser pulse returns within a frame. These two paths may be combined to provide a background image with a superimposed laser return.
摘要(中):
本发明的实施例描述了针对具有能够捕获目标的高速激光返回脉冲的单个相机的解决方案,以及提供目标背景上的成像信息。 通过具有能够从焦平面阵列(FPA)的像素中提取两种类型的信息的读出集成电路(ROIC)来实现该能力。 本发明的实施例描述了一种ROIC拓扑,其允许区分高频和低频信号路径的能力,并且提供支持电路来分别处理这两条路径。 一个路径可以集成低频背景场景以提供场景的高保真图像。 第二路径可以处理高频噪声并且在一帧内处理多个激光脉冲返回。 这两个路径可以组合以提供具有叠加的激光返回的背景图像。
