Cepton Technologies

The Silicon Valley Approach to Lidar Sensor Development

Cepton Technologies, Inc. is a fast-growing startup, founded in July 2016 to provide high-performance, high-resolution 3D lidar solutions for automotive, industrial and mapping applications. It produces four lidar sensors, the HR80T, HR80W and the brand new Vista for ground-based, primarily automotive applications, and the SORA 200 for UAV-based airborne use. Cepton stresses that its sensing principle has no rotation and thus no friction.
