SECO-RANGEFINDER-GEVK: SiPM Direct Time of Flight (dToF) LiDAR

The Direct Time of Flight (dToF) SiPM LiDAR Platform is a single point range finder development kit for cost-optimized industrial and commercial applications. The kit is based on the latest NIR SiPM from ON Semiconductor (RB series) and integrates all the essential sub-systems for the application involving laser and reference circuit (Tx), receiving circuit (Rx), power management systems, and core FPGA and UART communication. The kit is FDA certified and includes a multifunctional GUI enabling a complete evaluation of the range-finding performance as well as the adjustment of system variables such as the buffer number of pulses or the bias voltage for the SiPM-RB photomultiplier.
