Lidar solution targets industrial range finding
The SiPM dToF LiDAR Platform provides a complete solution for low cost, single-point LiDAR that OEMs can adapt and take into production to create industrial range finding applications. It includes the NIR laser diode, SiPM sensor and optics, as well as the digital processing necessary to convert the detected signals into elapsed time, and elapsed time into distance.
“Range finding using dToF LiDAR delivers on a critical need for many applications, extending from autonomous navigation through mapping to monitoring,” says Wiren Perera, who heads IoT at ON Semiconductor. “However, developing such a system based on dToF LiDAR can be challenging. This platform clearly demonstrates the effectiveness of this leadership technology. The availability of a proven design enables our customers to get to a proof of concept much faster, and rapidly deliver their product to market.”
The platform uses the company’s silicon photomultiplier (SiPM) sensor, which is designed to overcome shortfalls of traditional photodiodes by providing faster response times and high detection efficiency. The reference platform uses the company’s second generation of SiPM sensors, the NIR-enhanced RB-Series silicon photomultipliers, which deliver improved performance in red and the NIR range.
To accelerate customers’ time to market, says the company, it has made all of the design data for the reference platform available, covering the schematics, BoM, gerber files, and PCB design files. A PC-based GUI is also accessible, which provides a graphical representation of the measurements over time. The histograms generated provide further evidence of the system’s capabilities in applications such as range finding, collision detection, and 3D mapping.
The SiPM dToF LiDAR Platform can detect objects at distances between 10 cm and 23 m. It offers an out-of-the-box experience using the provided GUI, which allows engineers to start evaluating the technology immediately. The design is FDA Class 1 certified and compliant with IEC/EN 60825-1:2014 and 21 CFR 1040.10/ 1040.11 laser safety standards.
