Boresighting - Safran LRF 3013 Manual

LRF 3013 Integrator Manual
Mechanical stress due to tolerance and thermal expansion coefficient mismatches between the
module's and application's mechanical interface should be avoided as much as possible. An
undefined stress could result in a misalignment of the module's transmitter and receiver
channel and reduces the range performance.
Assembly personnel must be experienced in handling precision, sensitive electronic,
mechanical and optical assemblies.
Vibration and shocks outside the specified values can destroy or shift parts inside the LRF in a
way that proper use is no longer possible.

Boresighting

The module receiver and transmitter are boresighted in the factory. For this reason, the module and can
be mounted and replaced easily. For a professional boresighting of the LRF module with the main optical
axis of the host system, we recommend the use of a collimator and a camera that can see the 1'550 nm
wavelength of the laser module. Vendors of 1'550 nm cameras (SWIR cameras):

XenICs (www.xenics.com) (e.g. XEVA-1.7-320)

Sensors Unlimited (www.sensorsinc.com) (e.g. 640HS-1.7RT)

Allied Vision Technologies (www.alliedvisiontec.com) (e.g. Goldeye P-008 SWIR)
Collimators can be sourced from Möller Wedel Opical (http://www.moeller-wedel-optical.com).
Note: The LRF module provides a low power continuous lasing mode to make its line of sight visible to
SWIR cameras. Please see chapter 6.2.5 for details.
