However, high price tag of existing commercial LiDAR modules based on mechanical beam scanners and intensity-based detection scheme makes them unusable in the context of mas Qt1D67V62P_Nosplash_63Db99594C05Eb04B901Ecff982D110D.pdfs produced consumer products.The focus of thesis is on the integrated coherent LiDAR with optical phased array-based solidstate beam steering, which h

Motivated by this observation, a quantitative framework for evaluating FMCW LiDAR performance is also introduced to predict the design that satisfies car-grade performance requirements.
