AEye iDAR: Sensor Performance Validation Report 2021 (VSI Labs)

On February 3, 2021, VSI Labs, one of the nation’s leading active safety and automated vehicle technology experts, oversaw the performance testing of AEye’s iDAR system with emphasis on applications for safety and autonomy. The four performance specifications tested were: Detections at 1K Range at 10Hz; Resolution as measured by Points per Degree Squared, Speed as measured by Full Frame Scan Rate, and Sensor Integration Flexibility.

In all four performance tests, it was determined that the tests carried out by AEye employees, and witnessed by John Cooper and Matthew Linder of VSI Labs, were valid and that the objective was reached: 1) the AEye sensor was able to detect targets with a substantial number of points at a distance exceeding 1000 meters without compromising frame rate 2) AEye’s sensor produced over 175 points on an 18% target at a distance of 200m, achieving the metric with 1600 points per degree squared 3) iDAR achieved over 200Hz scan rate for full frame and field of view (FOV) and 4) the iDAR sensor works effectively behind a first-surface made of windshield glass material at a nominal thickness at various angles of incidence.

Based on its findings, VSI Labs determined that AEye’s iDAR system “achiev[ed] a range of more than four times, a resolution of more than five times, and scan rates of over ten times greater than LiDAR devices currently on the market. This data can be used by the automated vehicle to see further, gain more accurate information, and make decisions about its trajectory at a greater distance or at a higher velocity.”
