The [Pulsar SL450](https://www.orbbec.com/pulsar-sl450/) is a single-line LiDAR sensor. Single-line LiDAR measures depth across a single 2D plane, rather than a full 3D field. In exchange, they gain massive range compared to other depth sensors, making them suitable for installation in large spaces. The SL450 claims a depth range of up to 45 metres.
