What is Required for Autonomous Cars?300 meters (approximately 11 seconds at 60 mph) Higher output lasers Going to longer wavelengths (1440 nm vs 903 nm) allows for higheroutput power without danger to the human eye 1440 nm lasers are more expensive Edge emitting LEDs are more efficient than VCSEL and have superiorcolumnation VSEC lasers can be lower overall cost, but shorter range More sensitive detectors Geiger mode can detect single photons but takes time to “reset”Power Conversion Technology Leaderepc-co.com13
