We present a simple method for continuous snapshot multispectral imaging or multispectral videography that achieves high-speed spectral video recording without the need for mechanical scanning and much computation for datacube construction. The enabling component of this method is an array of periscopes placed in a prism-based spectral shaper that spectrally separates the image without image deformation. As a proof-of-principle demonstration, we show five-color multispectral video recording in the visible range (200×200 pixels per spectral image frame) at a record high frame rate of at least 2800 frames per second. Our experimental results indicate that this method holds promise for various industrial and biomedical applications such as remote sensing, food inspection, and endoscopy.
我们提出了一种用于连续快照多光谱成像或多光谱摄像的简单方法，该方法无需机械扫描和大量用于构建数据立方体的计算即可实现高速光谱视频记录。该方法的核心组件是一组放置在基于棱镜的光谱整形器中的潜望镜阵列，该阵列可在不产生图像变形的情况下对图像进行光谱分离。作为原理验证演示，我们展示了在可见光范围内（每个光谱图像帧200×200像素）以创纪录的至少每秒2800帧的高帧率进行的五色多光谱视频记录。我们的实验结果表明，该方法在遥感、食品检测和内窥镜检查等各种工业和生物医学应用中具有广阔前景。
