Quantum dot-enabled infrared hyperspectral imaging with single-pixel detection
Chinese Academy of SciencesThis study suggests single-pixel detection as a cost-effective alternative to expensive InGaAs focal plane arrays (FPAs) for near infrared (NIR) hyperspectral imaging. It achieves successful imaging with colloidal quantum dots (CQDs) and a digital micromirror device (DMD) for multiplexing, offering a 600 nm detection window and 8.6 nm spectral resolution at 128 × 128 pixels. This method promises accessible and affordable NIR hyperspectral imaging, broadening its applications.
