Open Hardware scanning laser rangefinder based on Time-of-Flight principle. No standalone laser rangefinder modules were used in this LIDAR, so its schematic and firmware are fully open.
Its parameters:
- Scanning speed: scans / second
- Resolution: ~ 1% of distance, but not better than ± 2 cm
- Minimal distance: 5 cm
- Maximal distance: ~ 90 m (white surface)
- Angular resolution: 0.5 deg
- Measurements frequency: ~ 25 kHz
- Scanning angular range: ~ 600 deg, could be increased by changing mechanics
- Power: 0.1 A at 5V (0.5 W). Start current could be bigger than 0.8 A.
- Size: 114 x 114 x 600 mm
Price of the components of this LIDAR is ~ $ (without delivery).
See BOM with all calculations: “TotalBOM.xlsx”.
This LIDAR is using COTS (Commercial Off-The-Shelf) optical components – standard lenses for surveillance cameras.
