Advanced Solutions to Increase Range Capabilities and Reduce Cost in ToF and FMCW LiDAR

HOSTED BY:

Cost, range, size, and reliability are all key challenges facing LiDAR design engineers. New technologies have emerged that address all these challenges in long-range ToF and FMCW LiDAR including a triple-junction, laser diode development and high-gain SOA arrays for military, medical, industrial, and automotive LiDAR applications. The shrinking cost of 1,550 nm sources is making 1,550 nm viable, especially considering the latest advancements in the triple-junction, laser diode sources. A benchmark study of 1,550 nm versus its 905 nm counterpart demonstrated that a LiDAR with a triple-junction, laser diode at 1,550 nm generated 80 times more photons, and more photons results in more pixels and a more robust 3D picture from point clouds. This 60-minute Webinar examines these and other advancements that innovations in triple-junction, laser diodes bring to LiDAR including increased range capabilities and lower costs.

Topics include:

  • New technology developments in triple-junction laser diodes
  • How the triple-junction diodes are immune to catastrophic optical damage
  • Reliability data on triple-junction laser diodes

A Q&A session will follow the technical presentation.
