论文摘要
我们证明了基于纤维束的频率调制连续波光痛的成像能力。激光雷达以60 Hz的速度构建了硬目标的速度和范围图像。感应范围高达30 m，具有20 mW的输出功率。该仪器使用七个平行的杂种接收器采用自定义电子设备。图像恢复的一个示例显示在旋转磁盘和无人机悬停在空中的6像素“图片”上。在实验中，我们还测试了用相锁环的激光调谐线性校正。我们将这种低分辨率系统的实用性视为传统激光痛的扫描速率或直接目标成像的提升，并进一步升级像素计数。
We demonstrate the imaging capability of a frequency modulated continuous wave lidar based on a fiber bundle. The lidar constructs velocity and range images for hard targets at a rate of 60 Hz. The sensing range is up to 30 m with 20 mW of output power. The instrument employs custom electronics with seven parallel heterodyne receivers. An example of image recovery is presented on 6-pixel "pictures" of a spinning disk and a drone hovering in the air. In experiments, we also tested the laser tuning linearity correction with a phase-locked loop. We see the practicality of such a low-resolution system as a boost in scanning rate of conventional lidars or for direct target imaging with a further upgrade of pixel count.
