Optical Survey Prism Applications
Surveying reflector prisms are used by surveyors and engineers to
measure the change in position of a target that is assumed to be
moving. Survey prisms are used for a wide range of monitoring
applications including:
·Rail Monitoring
·Settlement Monitoring
·Displacement Monitoring
·Deformation Monitoring
·Convergence Monitoring
Optical Surveying Reflector Prism Installation
Monitoring prisms should be installed using the following
guidelines:
·Attached to a rigid structure that is sufficiently stiff as to not
move through a single monitoring cycle
·Located to minimize the effects of temperature and radiant heat on
a target
·Installed with clear sight lines back to the total station
·Avoid sight lines that require shooting through a fence or another
mesh
·Avoid sight lines shooting just past corners which can cause
refraction
·Avoid sight lines that include a source of heat that can cause a
heat shimmer
