While it’s still early in the game, LiDAR remains a focal point as automotive manufacturers prepare to meet the anticipated demand for SAE Level 4 autonomy. The likelihood LiDAR will at least be in the mix is high. As a result, what is expected to be a $2.23 billion market in 2022 is estimated to reach $4.71 billion by 2030, representing a conservative CAGR of 9.8%. According to Grand View Research’s report, various performance-based concerns including the “increasing demand for 3D imagery, increasing deployment of automotive safety technology, and growing environmental concerns” serve as key drivers. Photonics professionals are keeping a close eye on the use of lidar because it is going to have a direct impact on the future of their business.
From an article in Laser Focus World by Peter Fretty.
Fortunately, LiDAR technology and component manufacturers continue to make great strides in addressing performance concerns including a track record of providing reliable driver assistance and constantly improving environmental sensing capabilities. And, the reality is, the technology behind today’s LiDAR solutions is still maturing.
However, when putting all the components together to achieve autonomy, a few potentially significant obstacles still exist, such as the need to miniaturize technology to fit within existing automotive model constraints. While the thirst for autonomy continues to grow, neither automakers nor consumers want the technology to significantly alter the aesthetics of a vehicle.
Why have we continued to dig into the various aspects of LiDAR? Simply put, those intimately familiar with the applicable photonics components are paying close attention. According to a recent survey of our readership, LiDAR is not just a significant area of interest for our engineering heavy audience, respondents also identify the technology as one of the most important for the future success of their companies.
The common technology for automotive LiDAR application is the pulse or time of flight (ToF). There are new emerging technologies to improve the performance of ToF LiDAR units. On the other hand, frequency-modulated continuous-wave (FMCW) is often seen as an alternative technology of ToF. While FMCW has performance advantages, the complexity difference between FMCW and ToF options is vast, creating a cost challenge.
