SURVEYING SYSTEM WITH BI-DIMENSIONAL SCANNING PROFILE

Abstract: a mobile surveying system is provided. the system comprises a first deflection unit, a second deflection unit, a laser source configured to generate a laser beam and a controller. the first deflection unit is arranged to deflect the laser beam onto the second deflection unit. the controller is configured to control the first deflection unit to rotate at a first frequency to vary a position at which the laser beam impinges the second deflection unit. the controller is configured to control the second deflection unit to rotate at a second frequency to scan the laser beam 360� about the mobile surveying system. the first deflection unit and the second deflection unit together provide a bi-dimensional scanning profile of the laser beam about the mobile surveying system. the first frequency and the second frequency are non-commensurable.
