Abstract
A compact LiDAR device is provided. The compact LiDAR device includes a first mirror disposed to receive one or more light beams and a polygon mirror optically coupled to the first mirror. The polygon mirror comprises a plurality of reflective facets. For at least two of the plurality of reflective facets, each reflective facet is arranged such that: a first edge, a second edge, and a third edge of the reflective facet correspond to a first line, a second line, and a third line; the first line and the second line intersect to form a first internal angle of a plane comprising the reflective facet; and the first line and the third line intersect to form a second internal angle of the plane comprising the reflective facet. The first internal angle is an acute angle; and the second internal angle is an obtuse angle.
