- 4. Time of flight Object at 2m distance is detected in 13ns; 16000 measures per second
- 5. Scanning Information: Direction LASER diode Mirror
- 6. Multiple curtains ex. at 4 m : distance between curtains = 40 cm o° 2° 4° 6° Not to scale o° 2° 4° 6° 0° 6°
- 7. What happens in 66ms Each curtain = 270 measures = 16377 measures
- 8. Advantages of this technology Good immunity against disturbances Background suppression Good immunity against reflectance factor of target object Very precise detection fields Adaptive detection fields Multi-curtains with possibility of different functions assigned Multiple detection fields Very simple installation (Plug & play) Teach-In Single point of installation (no separate parts for TX/RX)

- 20. Laser versus lightgrids Light Grids Damaged by Collision Laser Scanner Mounts at Top of Door, above Impact Points
- 21. Laser versus lightgrids Light Grids Miss Tall Objects Laser Scanner Detects Across Entire Opening
- 22. Laser versus lightgrids Light Grids Will Miss People Just Outside Threshold Laser Scanner Pattern has “Depth”
- 23. Laser versus lightgrids Debris, Leaves and Dust Collect in Track and on Light Grid Surface Laser Scanner is “Above” Most of Debris
- 24. Laser further applications Vertical LZR ; 2 units static on the gate frame The goal would be to fix one LZR on each side of the gate to cover the complete closing area on both sides. Safety solution type E. Horizontal LZR ; Barrier application The goal would be to replace induction loops with increased safety for pedestrians
- 25. Laser further applications A LZR scanner would be able to scan under the barrier (safety) and in front of the barrier (activation). Both fields are in presence detection. This concept is very interesting for the following reasons: Safety for people or presence detection on loop 1 Great flexibility. It could be installed everywhere. Cost of the installation/installation time Ideal for retrofit purpose Plug and play solution
- 26. Laser gate safety & monitoring application Vertical LZR ; 2 units static on the gate frame The goal would be to fix one LZR on each side of the gate to cover the complete closing area on both sides. Safety solution type E.
