Peregrine 3D Flash LIDAR Vision System™

ASC is the world’s leader in 3D Flash LIDAR cameras.  ASC designed the Peregrine family of 3D Flash LIDAR Video Cameras  as lightweight, low power 3D video cameras that output range (point cloud) and intensity in real-time for use in a wide range of applications ranging from aerial mapping to active safety to surveillance.  Peregrines are used by automotive companies to evaluate 3D Flash LIDAR cameras for their active safety and autonomous applications such as collision avoidance and lane departure warning systems.

Functional Description

The lightweight Peregrine camera is a solid state 3D staring array LIDAR camera with no moving parts other than a fan [i.e., it is not a scanning Lidar device].  Peregrines illuminate an area of interest represented by the field of view of the lens with a single short [5 nanosecond] Class I (eye-safe) laser pulse per frame and captures the reflected laser light in the form of 3D range point clouds and co-registered intensity data.  With 128 x 32 [4,096] pixels and a 4:1 aspect ratio, Peregrine cameras operate up to 20Hz.  Peregrines are configured with a choice of bayonet mount lenses options of 60°x15°, 45°x11.25°, 30°x7.5° and 15°x3.75°.

Specifications
