Optical Surve Prisms
Optical Survey prisms are a specially designed retro reflector, specifically a corner reflector, that is used to reflect the Electronic Distance Measurement (EDM) beam from a total station. A survey prism reflects the EDM beam back to its source with both a wide angle of incidence and with high precision. Prisms reduce the scatter of the beam as it is reflected back to the total which allows for both a more accurate measurement and a longer range that the measurement can be made.

Optical Survey Prism Applications

Survey 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 Survey 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
