Universal Laser Rangefinders (ULS)
The ULS is a user configurable laser rangefinder that has four primary measurement modes:
Averaging mode: the ULS takes a specified number of individual distance measurements and averages them into a single output result. Last target mode: used in poor environments to achieve a measurement to the last object the laser hits. Binning mode: allows the ULS to acquire a single specific target in the presence of multiple intervening unwanted targets (or system noise, in the case of an extremely weak target) by taking a ‘burst’ of individual measurements and determining the prominent target in the aggregate data set. Detection mode: a dedicated, rapid update, proximity detection configuration used to detect the presence of fast moving objects.
Accuracies of several cms at hundreds of meters are achievable.
