A Light Detection and Ranging LiDAR system (800) for detecting an object in a blind spot area is provided. The system includes a housing (810) and a scan-based LiDAR assembly disposed in the housing. A scanning-based LiDAR assembly includes a first light source (871), a multi-facet polygon (820), a window (830), a collimator lens (860), a combination mirror (850), an opening (852), a collection lens (840), a light detector (881), a laser circuit board (871), and a detector circuit board (880). The first light source (871) provides a plurality of light beams. A multi-facet polygon (820) is rotatable to scan the plurality of light beams to illuminate the FOV. The multi-facet polygon (820) and the first light source (810) are vertically stacked, preferably the first light source (810) is on top of the multi-facet polygon (820). A collimating lens (860) is optically coupled to the first light source (810) and collimates the plurality of light beams (890). One or more collection lenses (840) collect return light (895) generated based on illumination of the first FOV. A light detector (881) receives the collected return light (895). The polygon mirror (820) has four wedge-shaped facets with variable angles of inclination, and the LiDAR system requires a longer detection distance and a larger vertical field of view in order to detect objects in the blind spot area of the vehicle. Thus, the LiDAR (800) preferably further comprises a different wavelength based non-scanning based flash LiDAR component, which is also encapsulated in the housing (810) to maintain a compact design.
