Title: TIME FLIGHT METHOD-BASED LASER RADAR SYSTEM
Abstract:
A time flight method-based laser radar system, comprising: a laser (111) used for generating laser light; a light path scanning unit (10), which performs deflection control over an emission light path of laser light so as to emit laser light for a target object within a preset range; a reflected light receiving unit (20), which is coaxial with the emission light path of the laser light and is used for receiving reflected light of the target object as reflected by the light path scanning unit (10) and outputting an electrical signal; a signal processing unit (106), which generates distance information between a laser radar system and a target object according to an electric signal and which processes a plurality of distance information so as to generate position information of the target object within the preset range; and a housing (100), housing the laser (111), the light path scanning unit (10) and the reflected light receiving unit (20), the housing (100) being provided with a filter (109) between the light path scanning unit (10) and the target object. The laser radar system has a simple optical structure, is highly reliable and is low cost.
