Laser radar system based on VCSEL array chip

The utility model discloses a laser radar system based on a VCSEL (Vertical Cavity Surface Emitting Laser) array chip, and relates to the technical field of laser radars. Comprising a light source, a projection optical unit, a beam deflection unit and a detection unit. The light source, the projection optical unit and the detection unit are sequentially arranged, and the light beam deflection unit is arranged on the light source, the projection optical unit or an emergent light path of the projection optical unit; the light source is a VCSEL array type chip with multiple emission holes, and the light beam deflection unit at least has two motion dimensions. In order to solve the technical problem that an existing laser radar system is large in size, an integrated VCSEL chip array is utilized, and on the premise that existing laser radar technical indexes are maintained, the system structure complexity is reduced, the service life of a mechanical system is prolonged, and the system size is reduced. 本实用新型公开了一种基于
