Upconversion Optical Entropy Encoding for Infrared Complex-Amplitude Imaging
This paper introduces a revolutionary upconversion optical entropy encoding method for real-time infrared complex-amplitude imaging. Leveraging light scattering and lanthanide photoluminescence, it enables high-fidelity, video-rate capture of both amplitude and phase information from infrared scenes using cost-effective silicon photodetectors. The system demonstrates high photosensitivity and potential for autonomous driving applications.
