SiPM dToF LiDAR Platform Development Kit

Within the Internet of Things (IoT), there are an increasing number of ranging and sensing applications looking to benefit from low-power, high performance SiPM technology. In particular, LiDAR (light detection and ranging) applications that use eye-safe near infrared (NIR) wavelengths such 3D depth maps, mobile, consumer and industrial ranging.

The SiPM Direct Time of Flight (dToF) LiDAR Platform is a complete development kit for single point range-finding applications. The FDA-certified kit is based on the RB-series NIR-enhanced SiPM, and integrates all essential system components including laser and reference circuit (Tx), receiving circuit (Rx), power management systems, and core FPGA and UART communication.

Taking advantage of the SiPM sensor’s high gain and high bandwidth, direct time-of-flight (dToF) can be used to provide accurate ranging up to 23 meters without compromising battery life.

What is a Direct Time of Flight (dToF) Ranging System?

In direct ToF ranging systems, a periodic laser pulse is directed at the target, typically with eye-safe power and wavelength in the infrared region. The target diffuses and reflects the laser photons and some of the photons are reflected off of the target object in all directions back towards the sensor. The returned photons are detected by the receiving sensor, and converted to electrical signals that are then timestamped.

Applications

Indoor navigation and range-finding (up to 23 m)
Collision Detection
3D mapping
