Livox officially launched its full range of lidar sensors
Livox is a high-tech company dedicated to the development of laser radar (LiDAR) sensor technology. It is invested by well-known technology companies such as DJI and provides sales channel support. By developing innovative optoelectronic and optomechanical solutions, Livox offers a unique combination of cost, resolution, range, compactness, reliability and manufacturability. Designed for autonomous driving, robotics, drones, and surveying applications, Livox's Lidar series helps customers easily integrate lidar sensors into their pilot projects and volume production.
According to Mammus Consulting, Livox has announced the launch of its full line of lidar sensors, including the Mid-40 and Mid-100 series, which are excellent in performance and affordable, and Tele-15 for long-range detection (reflectivity 80%) Detecting distances up to 500 meters) and Horizon for larger fields of view (FoV).
Among them, the most concerned are the Mid-40 and Mid-100 sensor units, as they are priced at only $599 and $1,499, respectively. Now, Livox has already started to sell through DJI Mall, the investor's DJI. However, for domestic users, it may have to wait a second time, because the product series of DJI Mall shows "This product is temporarily out of stock or does not support sales. China Mainland".
Mid-40 and Mid-100
The Mid-40 is a more consumer-friendly option. It is small, measuring just 88 x 69 x 76 mm and is lightweight, weighing only 710 g, and can be mounted directly on a small drone. It has a slightly smaller field of view of 38.4° and a scan rate of 100,000 points per second. Its typical power consumption is 10 W.
The Mid-40 and Mid-100 are similar in many ways, because the Mid-100 is a system that integrates three Mid-40 sensors. The detection distance of the two is up to 260 m at a reflectance of 80%, the detection distance is 130 m and 90 m at a reflectance of 20% and 10%, the distance accuracy is 2 cm, and the angular accuracy is less than 0.1°.
The Mid-100 integrates three Mid-40s, so it is larger and more expensive to achieve higher performance metrics. It measures 142 x 70 x 230 mm, weighs 2,200 g and has a horizontal field of view of 98.4°. It has a scan rate of 300,000 points per second and a typical power consumption of 30 W.
Livox Lidar's unique repeat-free scanning mode
The unique scanning trajectory and mode of the Livox lidar sensor is promising for many applications that require high field of view coverage. The scanning trajectory of Livox Lidar is not repeated during use, so it is called “no repeat scan mode”. The no-repetitive scan mode provides significantly increased field of view coverage over time compared to conventional mechanical scanning schemes used in most LiDAR sensors on the market.

For example, in the above figure (a), the repeat-free scanning mode is adopted, and the field of view coverage increases significantly with time; however, in Figure (b), the field of view coverage is almost no matter how the integration time changes. change.
Mass production ready
According to Mamms Consulting, a major problem faced by laser radar manufacturers in mass production of products is the need to accurately align the laser/receiver (<10 um accuracy) in a space of approximately 10 cm or slightly larger. . Most of the most advanced lidar sensors currently on the market are usually manually completed by skilled technicians. Livox's lidar sensors eliminate this alignment process by using a unique scanning solution and a "DL-Pack" solution, enabling mass production of sensors. The DL-Pack solution is a multi-laser and multi-avalanche photodiode (APD) package technology developed entirely by Livox to support the mass production of its lidar.
The Mid-40 and Mid-100 sensor units do not require any time-consuming multi-line laser calibration and do not contain any moving electronic components. This fundamentally improves the manufacturability of the device and facilitates mass production of the product. Currently, the Mid-40 and Mid-100 sensor units are ready for volume shipments.
From system-level operation to each individual component, the Mid-40 and Mid-100 are designed for ultra-high reliability. Specifically, it is an electronic component that does not contain any motion. Its products have undergone high temperature endurance testing, salt spray testing and other stringent reliability tests required by the automotive industry. In addition, the Mid-40 and Mid-100 lidar sensors have achieved IP 67 waterproof and dustproof under GB 4208-2008 and IEC 60529 standards.
Adapt to various environments
Mid-40 and Mid-100 lidar sensors maintain stable performance in a wide range of lighting conditions, from 100 kilolux to low visibility environments. With built-in innovative noise reduction algorithms, Mid-40 and Mid-100 are effective in reducing noise caused by atmospheric particles such as rain, fog and dust, as well as interference from other lidars.
Examples of Livox's full range of lidar sensors include autonomous vehicles, (large) drones, search and rescue, and high-precision mapping. At present, there is still a shortcoming in the Mid series of sensors. Although they have already landed in the DJI mall, users can directly choose to purchase them, but they have not been officially put into mass production. These sensors are just "mass production ready". This may be just before Livox tests the market feedback through news releases or other means before the scale.
