| Laser wavelength | 1535 nm |
| Laser beam divergence | 0.25 mrad (1/e²) |
| Size of the laser dot | Φ 41 mm at 120 m (1/e²)
Φ 86 mm at 300 m (1/e²) |
| Detection range | 700 m at 10 % reflectivity, 350 kHz
950 m at 10 % reflectivity, 100 kHz
2000 m at 80 % reflectivity, 100 kHz
1. definition of range: The distance at which 50 % of the emitted laser pulses are detected. If a laser beam hits several objects, the total power of the laser transmitter is divided, which reduces the achievable range.
2. test conditions: 100 klx ambient brightness, in the central area of the field of view, with a flat object larger than the diameter of the laser beam, at a vertical angle of incidence and an atmospheric visibility range of 23 km.
3. the maximum detection range is 900 m as standard. For a longer range, please contact DJI Support or an authorized dealer. |
| Detection range for cables | 21.6 mm aluminum steel core stranded wire:
300 m at 100 klx, 350 kHz
18.4 mm black PVC insulated wire:
100 m at 100 klx, 350 kHz
1. definition of range: The distance at which a fully scanned section of wire reaches a point density of 4 points per meter.
2. test conditions: 100 klx ambient brightness, 23 km atmospheric visibility, LiDAR center looking perpendicular to the wire, non-repetitive scan mode, drone flying at 15 m/s along the wire, and the wire is clean and undamaged. |
| Distance accuracy | Absolute accuracy: ±10 mm
Repeatability: < 5 mm (1σ)
