We demonstrate an imaging system employing continuous high-rate photonically-enabled compressed sensing (CHiRP-CS) to enable efficient microscopic imaging of rapidly moving objects with only a few percent of the samples traditionally required for Nyquist sampling. Ultrahigh-rate spectral shaping is achieved through chirp processing of broadband laser pulses and permits ultrafast structured illumination of the object flow. Image reconstructions of high-speed microscopic flows are demonstrated at effective rates up to 39.6 Gigapixel/sec from a 720-MHz sampling rate.
我们展示了一种采用连续高速光子压缩感知（CHiRP-CS）的成像系统，该系统仅需传统奈奎斯特采样所需样本的百分之几，就能对快速移动的物体进行高效显微成像。通过对宽带激光脉冲进行啁啾处理实现了超高速率光谱整形，并允许对物体流进行超快结构照明。从720兆赫兹的采样率开始，以高达39.6千兆像素/秒的有效速率展示了高速微观流的图像重建。
