摘要
En 中文
We proposed a concurrent transmitting-based 128 channels LiDAR using an bipolar optical code scheme called code-inversion keying based prime-permuted code, which is the most suitable method to shorten the chip sequence length, while maintaining the performance characteristics of LiDAR. In each channel, four laser diodes with different wavelengths are bundled with a coupler to direct toward a target direction. The target direction could be recognized after the reception by identifying the received reflected pulse, even if several target directions were measured simultaneously. Due to the very short chip sequence, only a very short signal transmission time is required.
