For the first time, a thorough study of laser eye safety between 1550nm and 905nm and its performance benchmark in automotive LiDAR was reported by SemiNex Corporation and prominently published in Laser Focus World Magazine. The analysis compares the newly developed 1550nm triple junction laser diode and 905nm on key performance inputs including the eye safety levels, photon budget over the detection range, target reflectivity, and atmospheric media. The LiDAR system model with typical system parameters is then benchmarked based on the signal-to-noise ratio and probability of detection with potentially industry-transforming results.
The study demonstrates that a high-power laser diode with triple junction at eye-safe 1550nm can generate 50 times more photons per second and detect 3 times longer distance than their 905nm counterpart in a controlled head-to-head comparison. This breakthrough in 1550nm diode lasers by SemiNex allows the LiDAR industry to look beyond 200m of detection distance with a single low-cost emitter and opens up a whole array of long-range applications including high-speed autonomous vehicles.
The benchmark study is featured in the November issue of Laser Focus World Magazine and available online at www.laserfocusworld.com. Details on the triple junction laser diodes is available at www.seminex.com. For more information and product availability, contact firstname.lastname@example.org.
