Optical Surveying Reflector 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 MonitoringSettlement MonitoringDisplacement MonitoringDeformation MonitoringConvergence Monitoring
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 cycleLocated to minimize the effects of temperature and radiant heat on a targetInstalled with clear sight lines back to the total stationAvoid sight lines that require shooting through a fence or another meshAvoid sight lines shooting just past corners which can cause refractionAvoid sight lines that include a source of heat that can cause a heat shimmer
