摘要： Compressive imaging captures images in compressed form, where each sensor does not directly correspond with a pixel, as opposed to standard image capture techniques. This can lead to faster image capture rates due to lower I/O bandwidth requirements, and avoids the need for image compression hardware, as the image is captured in compressed form. Measuring the transformation of an emitted multimodal signal is one method of compressive imaging. Metamaterial antennas and transceivers are well suited for both emitting and receiving multimodal signals, and are thus prime candidates for compressive imaging.
摘要翻译：与标准图像捕获技术相反，压缩成像以压缩形式捕获图像，其中每个传感器不直接对应于像素。由于较低的I / O带宽要求，因此可以获得更快的图像捕获率，并且避免了图像压缩硬件的需要，因为图像以压缩形式被捕获。测量发射的多峰信号的变换是压缩成像的一种方法。超材料天线和收发器非常适合发射和接收多模态信号，因此是压缩成像的首选。

摘要： Multi-sensor compressive imaging systems can include an imaging component (such an an RF, microwave, or mmW metamaterial surface antenna) and an auxialiary sensing component (such as an EO/IR sensor). In some approaches, the auxiliary sensing component includes a structured light sensor configured to identify the location or posture of an imaging target within a field of view of the imaging component. In some approaches, a reconstructed RF, microwave, or mmW image may be combined with a visual image of a region of interest to provide a multi-spectral representation of the region of interest.
