Product overview
The Leishen Intelligent System LS-S4 is a long-range LiDAR sensor built around the manufacturer’s own 1550 nm fiber laser. Its sensing purpose includes detecting low, slow, and small targets and producing point-cloud images of moving targets. The laser is classified as Class 1. Maximum detection range is 1500 m, with range accuracy specified at ±5 cm. These figures describe different measurement characteristics: the detection distance defines reach, while range accuracy describes precision in the distance measurement.
For physical integration, the LS-S4 weighs 3 kg and occupies a rectangular envelope measuring 219 × 149 × 85 mm in length, width, and height. Its point-cloud output reaches a maximum of 6,000,000 points per second, and its maximum frame rate is 20 Hz. Minimum angular resolution is specified separately for each axis: 0.036° horizontally and 0.0487° vertically. The range, frame-rate, and output figures are maximum values; the angular-resolution figures are minima, preserving the distinct limits relevant to selecting this sensor.
