Reflective targets are essential tools for geodetic monitoring, laser scanning, and long-range measurements. They offer a simple but very effective way to establish fixed reference points. No matter if you, as a surveying professional, are conducting as-built documentation, structural monitoring, or tunnel alignment, reflective targets will help you achieve precise and repeatable positioning for any of your surveying instruments.
Designed for compatibility with laser scanners, total stations, and monitoring systems, these targets come in various sizes, colors, and adhesive formats to meet diverse application needs in the field.
What Are Reflective Targets?
Reflective targets are flat or patterned surfaces with highly reflective coatings or designs, used as fixed points that reflect the laser or optical signal back to the measuring instrument. Depending on the use case, they are available as:
-
Self-Adhesive Reflective Targets: Peel-and-stick targets that are ideal for fast setup on walls, structures, or pavements.
-
Retro-Reflective Foil Targets: Designed for long-distance scanning with minimal signal loss.
-
Monitoring Targets: Used for deformation tracking over extended periods of time.
-
Pole-Mounted Targets: For mobile setups or temporary control points during construction.
These targets do not function as prisms but provide comparable accuracy for most monitoring and scanning applications, especially when prisms are impractical.
Why Use Reflective Targets in Surveying?
Reflective targets provide a cost-effective and versatile solution for many surveying and monitoring tasks. Key advantages include:
✔ High Accuracy – Delivers millimeter-level precision for scanning and total station measurements.
✔ Ease of Use – Quick to apply, especially in self-adhesive form with no added tools or setup required.
✔ Multi-Surface Compatibility – Can be placed on concrete, metal, glass, wood, or plastic.
✔ Visibility in All Conditions – Available in multiple colors, reliable for daylight or low-visibility environments.
✔ Compact & Portable – Lightweight and easy to store and even carry to remote sites.
✔ Cost-Effective – Ideal for use in large-scale monitoring grids and temporary site setups.
How Reflective Targets Work?
Reflective targets work by bouncing back laser or infrared signals emitted by a total station or scanner. Here's how they function:
-
Signal Emission: The instrument sends a laser or optical beam toward the reflective target.
-
Signal Reflection: The reflective surface bounces the signal back to the instrument.
-
Precise Measurement: The time-of-flight or phase shift is calculated, resulting in accurate positional data.
This system is designed that way that it allows repeated measurements of the same point, which ensures reliable monitoring over time.
Applications of Reflective Targets
Reflective targets are widely used in a variety of ways, but are most adept for the following surveying and engineering scenarios:
✅ Structural Health Monitoring: Tracks movement or deformation in bridges, dams, and tunnels.
✅ Laser Scanning Projects: Provides fixed reference points for 3D scanning and model alignment.
✅ Construction Alignment: Ensures precise layout of structures and components.
✅ Tunnel and Subway Projects: Marks permanent monitoring positions in confined spaces.
✅ Facade and Building Surveys: Applied on buildings to assist in vertical and horizontal scanning.
Choosing the Right Reflective Target
When selecting a reflective target for a project that you are planning to do, you should consider the following aspects:
📌 Size & Shape – Smaller targets should be used for tight areas, while larger are much better for long-range visibility.
📌 Color Options – Choose white, black, yellow, or red colored targets for better visibility under different lighting conditions.
📌 Material Type – Reflective foil helps for maximum distance, while plastic-based targets are for durability.
📌 Mounting Method – Self-adhesive targets are meant for quick application, while screw-mounted ones are best for permanent installation.
📌 Scanning Range – Select targets with reflectivity that is specifically optimized for your instrument's range.
