Light detection and ranging (LiDAR) technology that incorporates aspects of both solid-state and conventional LiDAR systems are referred to as hybrid solid-state LiDAR. LiDAR is a type of remote sensing that employs lasers to map the surroundings at high resolution and estimate distances.
A hybrid solid-state LiDAR system incorporates solid-state components to improve the functionality and potential of the LiDAR sensor. Microelectromechanical systems (MEMS) mirrors or optical phased arrays are examples of solid-state components that can be used in solid-state LiDAR sensors to direct and produce laser beams without the use of mechanical moving parts.
In a hybrid LiDAR system, the inclusion of solid-state components can have various benefits. Solid-state components have fewer moving parts and are less prone to wear and tear than classic mechanical LiDAR systems, which increases reliability and durability. This may lead to better long-term performance and less need for maintenance.
The potential for lightweight and small designs is another benefit. Compared to mechanical LiDARs, solid-state LiDAR systems can be more compact, allowing for integration into more compact machines or vehicles.
The advantages of solid-state components are frequently combined with the range and resolution capabilities of conventional LiDAR systems in hybrid solid-state LiDAR systems. This implies that they may take advantage of the advantages of solid-state technology while also offering precise distance measurements and high-resolution 3D mapping of the surroundings.
The growing need for LiDAR sensors in numerous applications, including autonomous vehicles, robotics, and industrial automation, is what is driving the development of hybrid solid-state LiDAR.
LiDAR will become more widely available and useful for a variety of applications with the help of the combination of solid-state and conventional LiDAR technologies, which aims to offer a balance between performance, reliability, size, and cost-effectiveness.
The Global Hybrid Solid State LiDAR Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Both the 905 nm LiDAR CX series and the 1550 nm LiDAR “Terminator 1” were released by LSLiDAR. LSLiDAR debuts at the Shanghai Auto Show with two of its bestselling products: the lightweight CX series 905 nm hybrid solid-state LiDARs and the image-grade Terminator 1 1550 nm fiber laser auto-grade LiDARs.
1550 nm fiber laser auto-grade LiDARS uses a 1550 nm fiber laser as its emission source.
The LiDAR’s strengths in precise collimation, high brightness, and strong anti-interference capabilities allow it to have longer detection ranges, higher resolution, finer perception of small objects, and superior anti-optical interference, which results in a clearer perception of the environment and longer braking distance, both of which significantly increase driving safety.
Conventional lidar systems have been hindered by high costs and low manufactureability. The AT128 hybrid solid-state directional lidar from Hesai has a tiny form factor, high point density, and a 200m range at 10% reflectance.
Each AT128 contains 128 high-power multi-junction VCSEL arrays from Lumentum that emit light at 905 nm. In order to meet the high-affordability, automotive grade dependability, and consistency requirements, the hybrid solid-state lidar AT128 for ADAS applications uses an all-VCSEL-based design.
The automotive-grade hybrid solid-state lidar AT128 integrates 128 laser channels for a total resolution of 1200×128 and a detection range of 200 meters using Hesai’s self-proprietary semiconductor technology.
It can efficiently record information of the objects within the field of view to provide strong perception capabilities for highly automated driving, speeding up algorithm iterations.One of the most competitive and complete lidars is the AT128 thanks to its highly integrated transmit-receiver module and reliable scanning structure.
The FT120, a fully solid-state near-range blind spot lidar created for ADAS series production vehicles, was formally unveiled by Hesai Technology.
The FT120 lidar has no internal moving parts and is entirely solid-state. It boasts a 100° x 75° ultra-wide field of view (FOV) and is intended for use in close-range blind spots. Leading OEMs have committed over a million units of estimated volume for the FT120.
The overall number of components in FT120 is significantly less than in conventional lidar. This design greatly increases product consistency, production efficiency, and reliability because there are no moving parts within.
The FT120 is based on a highly integrated architecture and offers excellent performance while being small. It may be encircled by the body of the vehicle or embedded on both sides.
Ford is getting closer to having a completely autonomous vehicle ready for production with the addition of the newest generation of computers and sensors, including the more compact and cost-effective Solid-State Hybrid Ultra PUCK Auto sensors.
Last but not least, Velodyne is already producing solid-state LiDAR technology as evidenced by the sensor’s “solid-state hybrid” moniker.
