3.1.1 Laser head
The laser head is where the FiX1’s laser is housed. The laser head spins vertically on the vertical pivot, by which it
is attached to the FiX1 body.
The measuring laser is an infra-red ‘time of flight’ device.
Laser pulses are fired through the transmitting optics. The laser pulses hit the targeted surface where they are
scattered. A tiny fraction of the scattered pulse reflects back into the FiX1’s receiving optics. The measured range
is derived from the time taken for the pulse to return to the laser, multiplied by the speed of light.
The laser measures between 5,000 and 15,000 points per second. The maximum distance that the laser can
measure is 250 m. Typically, ranges are measured to an accuracy of 1 cm.
The laser head rotates vertically on the vertical pivot which joins the laser head and the FiX1 body. Avoid placing
strain on the vertical pivot when handling the unit.
The laser head is surrounded by a sun shield which protects the body of the laser from direct sunlight.
3.1.2 FiX1 body
The FiX1 body rotates on the horizontal pivot which joins the FiX1 body and base.
The FiX1 body is connected to the laser head by the vertical pivot.
