New Method for 3D Imaging - Laser Light Absorption by Atmospheric Oxygen

Researchers developed a 3D camera using light absorption of atmospheric oxygen with a current-tunable single frequency distributed feedback laser. They achieved a distance accuracy of better than 4 cm between measuring distances of 4 m and 10 m.

The need for practical and functional 3D cameras is steadily increasing as automation and mobile applications demand cheaper, more compact, and more accurate techniques. Researchers in Espoo, Finland have developed a 3D camera using light absorption that creates a novel solution in 3D imaging for short to medium ranges (0 - 10 m). The laser provides active illumination for the laser light absorption of oxygen at 761 nm while a silicon-based image sensor captures the light. This design provides a compact and low-cost solution to complement LiDAR and stereo vision cameras.
