摘要

我们使用我们的III/V-on-Si光学相控阵(OPA)实现了紧凑，高精度的光探测和测距(LiDAR)模块。我们的模块只有1.4升的体积，我们展示了20米的范围和10米的3D成像，在100 klx的强光下，精度为1厘米。通过采用基于子分类的数字信号处理(DSP)，准确度比我们之前的工作[1]提高了300%。小尺寸和强大的3D深度传感性能保证了强大的商业可行性。

Palm-sized LiDAR module with III/V-on-Si optical phased array

We have implemented a compact, highly accurate light detection and ranging (LiDAR) module using our III/V-on-Si optical phased array (OPA). Our module measures only 1.4 liter in volume, and we demonstrated 20-m ranging and 10-m 3D imaging with 1-cm accuracy under 100-klx bright sunlight. The accuracy was improved by 300% from our previous work [1] by employing sub-binning-based digital signal processing (DSP). The small size and its robust 3D depth-sensing performance promise strong commercial viability.
