Laser Radiation Fields
The four beams generated by the Scanner electronics for tracking, are produced using
laser diodes with a typical operating wavelength of 785 nm. Each tracking laser is spread
into a fan-like pattern, with a beam divergence of approximately 100 degrees in one
direction. These fan beams are scanned vertically through the target area, by reflecting
off a rotating mirrored shaft. This produces an angular coverage or field of view of
±60°deg vertical and ±50° horizontal. Fans are at 15 degrees from the axis of shaft
rotation. The shaft rotates at 60Hz.

An interlock is designed into the laserBIRD Scanner which disables the lasers if the
scanner shaft is not rotating appropriately. This is a safety feature, and can not be
disabled.
