Abstract Coherent light detection and ranging (LiDAR). particularly the frequency-modulated continuous-wave LiDAR. is a robust optical imaging technology for measuring long-range distance and velocity in three dimensions (3D). We propose a spatio-spectral coherent LiDAR based on a unique wavelength-swept laser to enable both axial coherent ranging and lateral spatio-spectral beam scan... https://emporiumsmokeshopstles.shop/product-category/carb-caps/
