There is a tendency to use high-frequency piezoelectric, acoustic, and optical sensors to measure aeolian sand transport rates in the aeolian community. However, most of these sensors are particle counters with inconsistent sensitivities or low saturation limits. Here we introduce a commercial laser sheet sensor (LASS) that can be deployed streamwisely to measure local saltation flux or perpendicularly to capture the bulky character of sand streams. Our laboratory and field experiment results show that LASS sensors respond linearly to the sand flux over the range of 0–20 kg m⁻² s⁻¹, covering most saltation events in nature. The LASSes are extremely consistent. They maintain their functionality even with minor lens contamination or laser misalignment during deployment. LASSes should not be deployed in environments with poorly sorted or moist sand or non-unidirectional wind.

有一种趋势是使用高频压电，声学和光学传感器来测量风沙群落中的风沙运移速率。但是，大多数这些传感器是灵敏度不一致或饱和度极限较低的粒子计数器。在这里，我们介绍了一种商用激光薄片传感器（LASS），可以将其沿流方向部署以测量局部盐分通量，或垂直部署以捕获沙流的庞大特征。我们的实验室和野外实验结果表明，LASS传感器在0–20 kg m ^-2 s ^-1范围内对砂通量具有线性响应涵盖自然界中的大多数盐化事件。LASS非常一致。即使在部署过程中受到轻微的镜头污染或激光未对准的影响，它们仍能保持其功能。LASS不应部署在沙质较差或潮湿或单向风的环境中。
