Patent attributes
A plurality of beams of illumination light are emitted from a LIDAR device over a range of angles and scanned about an axis of rotation. The range of angles includes the axis of rotation. Intermediate electronics boards provide mechanical support and electrical connectivity between a rotating electronics board and various elements of a light emission and collection engine. One or more of the optical elements of the collection optics, the illumination optics, or both, is constructed from one or more materials that absorb light outside of a predetermined wavelength range. An overmolded lens is fixedly coupled to one or more of the light detecting elements to collect incoming light over a larger range of angles. A lens element is disposed in the light path between a light emitting element and the illumination optics to flatten the intensity distribution of light emitted from the light emitting element to reduce peak intensity.
