Abstract: An optical component includes a first lens and a second lens that are arranged in sequence in an emission direction of a beam and are disposed opposite relative to each other. The first lens has a first shaping surface and a second shaping surface that are disposed opposite to each other, and the second lens has a third shaping surface and a fourth shaping surface that are disposed opposite to each other. The first shaping surface and the third shaping surface form a first shaping surface group to perform optical path collimation on a first polarization direction of the beam. The second shaping surface and the fourth shaping surface form a second shaping surface group to perform optical path collimation on a second polarization direction of the beam.

Abstract: A ranging system and a mobile platform are provided. The ranging system includes a laser, a coaxial optical lens group, a mirror group, a moving component, and a processing circuit. When the laser emits laser light to the mirror group by using the coaxial optical lens group, the moving component drives the mirror group to rotate, so that the laser light is irradiated to a measured object at different angles, to implement ranging of the measured object. The moving component bears a light object, so that the moving component rotates quickly. Therefore, if the ranging system is installed on a vehicle, the ranging system can implement fast ranging of incoming and outgoing vehicles and meet a ranging requirement of an autonomous driving technology.
