| 摘要 |
An optical device, comprising an optical device, comprising an optical beam sweeper that includes a multi-wavelength laser source and an optical power splitter. The optical power splitter has an optical input optically coupled to the multi-wavelength laser source, the optical power splitter having N optical outputs, each optical output connected by a corresponding optical pathway of a parallel array to an optical output surface of the optical beam sweeper. N parallel optical paths connect the optical input to the optical output surface, each optical path including a corresponding one the optical pathways and having a different optical path length than the one or more other optical paths, the optical path lengths differing in a wavelength-dependent way. |
