Hesai said in a press release that the LiDAR sensor is a necessary part of autonomous vehicles. However, conventional LiDAR approaches are limited in their mass application by high costs and below-average levels of integration. Incorporating VCSEL array light sources, next-generation LiDAR designs can dramatically improve product integration levels, making them affordable and scalable, greatly increasing LiDAR’s competitiveness in the ADAS market.
Over the past few years, more than one billion Lumentum VCSEL arrays have been widely deployed in mobile communications, consumer electronics, industrial applications, and more. In the meantime, Lumentum’s advancements in VCSEL array technology have achieved record-breaking optical power densities and peak efficiencies, making it compatible with high-performance ADAS applications and autonomous vehicles.
Hesai’s AT128 is a hybrid solid-state directional LiDAR that features a 200-meter range at 10% reflectivity, high point density (>1.5M points per second), and small form factor. Each AT128 integrates 128 Lumentum VCSEL arrays emitting at 905 nm.
Over the past few years, Lumentum’s VCSEL arrays have accumulated massive shipping experiences in the consumer electronics market. The experiments helped the company build its multi-junction VCSEL network.
Currently, Hesai’s AT128 has landed supply orders from multiple automakers, amounting to millions of units in total, with full-scale production and delivery beginning in 2022.
