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
