Both 3D imaging and hyperspectral imaging provide important information of the scene and combining them is beneficial in helping us perceive and understand real-world structures. Previous hyperspectral 3D imaging systems typically require a hyperspectral imaging system as the detector suffers from complicated hardware design, high cost, and high acquisition and reconstruction time. Here, we report a low-cost, high-frame rate, simple-design, and compact hyperspectral stripe projector (HSP) system based on a single digital micro-mirror device, capable of producing hyperspectral patterns where each row of pixels has an independently programmable spectrum. We demonstrate two example applications using the HSP via hyperspectral structured illumination: hyperspectral 3D surface imaging and spectrum-dependent hyperspectral compressive imaging of volume density of participating medium. The hyperspectral patterns simultaneously encode the 3D spatial and spectral information of the target, requiring only a grayscale sensor as the detector. The reported HSP and its applications provide a solution for combining structured illumination techniques with hyperspectral imaging in a simple, efficient, and low-cost manner. The work presented here represents a novel structured illumination technique that provides the basis and inspiration of future variations of hardware systems and software encoding schemes.

通过结构化照明同时进行3D空间和高光谱成像的高光谱投影仪

3D成像和高光谱成像均提供了场景的重要信息，将它们结合起来有助于帮助我们感知和理解现实世界的结构。先前的高光谱3D成像系统通常需要高光谱成像系统，因为检测器遭受复杂的硬件设计，高成本以及高采集和重建时间的困扰。在这里，我们报告基于单个数字微镜设备的低成本，高帧速，设计简单且紧凑的高光谱条纹投影仪（HSP）系统，该系统能够产生高光谱图案，其中每行像素具有独立的可编程频谱。我们通过高光谱结构化照明演示了使用HSP的两个示例应用程序：参与介质体积密度的高光谱3D表面成像和光谱相关的高光谱压缩成像。高光谱图案同时对目标的3D空间和光谱信息进行编码，仅需要灰度传感器作为检测器。报道的HSP及其应用程序提供了一种以简单，有效和低成本的方式将结构化照明技术与高光谱成像相结合的解决方案。此处介绍的工作代表了一种新颖的结构化照明技术，该技术为硬件系统和软件编码方案的未来变化提供了基础和灵感。报道的HSP及其应用程序提供了一种以简单，有效和低成本的方式将结构化照明技术与高光谱成像相结合的解决方案。此处介绍的工作代表了一种新颖的结构化照明技术，该技术为硬件系统和软件编码方案的未来变化提供了基础和灵感。报道的HSP及其应用程序提供了一种以简单，高效和低成本的方式将结构化照明技术与高光谱成像相结合的解决方案。此处介绍的工作代表了一种新颖的结构化照明技术，该技术为硬件系统和软件编码方案的未来变化提供了基础和灵感。
