Multi-wavelength Compression Imaging and 3D Reconstruction Based on Lanthanide Transducers

Multi-wavelength, multi-channel, and multi-depth imaging techniques are essential in the research of three-dimensional reconstruction and comprehensive information representation of target objects. However, traditional techniques are generally limited by cumbersome combinations of costly and bulky components. In this preview, we highlight an excellent imaging technique named “stochastic photoluminescence and compressed encoding” or SPACE. By combining four randomly arrayed lanthanide transducers as photonic encoders with a compressed sensing reconstruction algorithm, the proposed technology enables efficient ultra-broadband, multi-wavelength compression imaging and information reconstruction.
