LIDAR Sensor System Including Particular Optic Design

A Light Detection and Ranging (LIDAR) system for a vehicle includes a housing and a micro optics assembly including a first portion and a second portion. The first portion includes: a light source to emit a beam along a first path, a first optical component to direct the beam emitted by the light source, an optical isolator to allow the beam directed by the first optical component to pass through the optical isolator along the first path and to prevent light from being reflected back into the light source through the optical isolator, and a second optical component to direct the beam after having passed through the optical isolator. The second portion includes an optical chip assembly including a plurality of chips to receive the beam along a second path, different from the first path, after having been directed by the second optical component.
